* AuthorsSavingThrow:
** Sentai's original home video release for ''LightNovel/ChuunibyouDemoKoiGaShitai'' was a subtitle only release. However after [[InternetBackdraft fans told Sentai that it was a very popular series deserving of a dub]], Sentai re-released in the series in a limited edition boxset which included an English dub.
** Averted with ''Manga/MonthlyGirlsNozakiKun''. Initially Sentai was planning on releasing the series subtitle only but due to its unexpected popularity among audiences and the demand for a limited edition, Sentai decided to not only give the series an English dub but a limited edition boxset.
** After a long time of waiting for a home video announcement of ''LightNovel/AmagiBrilliantPark'', Sentai was able to make fans feel the wait was worth it by announcing a very-content filled limited edition set for the series.
* AwesomenessWithdrawal:
** One problem fans have with Sentai is that whenever they dub an anime, the home video release is long after the anime has peaked in popularity. Best demonstrated with their licenses of anime that aired in 2015. Throughout 2016, Sentai released almost all of their shows from that year that were getting subtitle-only releases but for shows getting dubs, fans have to wait two years since the show began airing. Though some have defended this by saying that it helps Sentai put out higher quality dubs for their popular shows and fans do forgive this if the show gets a nice limited edition.
** ''LightNovel/AmagiBrilliantPark'' was an infamous example throughout most of 2015 and early 2016. Not only was the show not announced to have a licensor a half-year after it aired but Sentai didn't announce the video release for it until more than a year after the acquisition. The release itself is set for a bit more than two years after the show's initial broadcast. Though again, a lot of fans did forgive Sentai for the nice limited edition set.
** Inverted with ''Manga/AkameGaKill'' and ''{{Manga/Parasyte}}''. Both are Sentai's most popular recent titles and were aired on Toonami right off the bat both airing exactly a year after the Japanese broadcast. The home video releases were also released at a reasonable time as well.
* BrokenBase:
** -Steven Foster was possibly the most infamous ADR Director in the anime industry, as he was either seen as an example of {{Woolseyism}} with shows like Manga/CromartieHighSchool and Manga/HighSchoolOfTheDead, or the face of everything wrong with dubs due to his use of ObligatorySwearing and awkwardly placed Pop Culture references. (To put it in perspective, ''VisualNovel/{{Clannad}}'''s dub became better received after he was replaced by Janice Williams). This became moot after he left the company.
** While Creator/{{Funimation}}, Creator/VizMedia, and even Creator/AniplexUSA have had at least one of their properties aired on Creator/AdultSwim's Creator/{{Toonami}}, Creator/SentaiFilmworks had yet to have any. Some fans feel that Sentai's catalog is too niche to be Toonami worthy (the block tends to stick with more mainstream shows like ''Manga/AttackOnTitan'', ''Manga/BlackLagoon'', and [[Anime/DragonBallKai popular]] [[Manga/{{Bleach}} shonen]] [[Manga/{{Naruto}} titles]] in [[Manga/OnePiece general]]), and that bad blood between the two going back to Sentai's days as Creator/ADVFilms would hamper any sort of working relationship, while others think titles such as ''Manga/HighSchoolOfTheDead'', ''Anime/Persona4TheAnimation'', ''Anime/GatchamanCrowds'', ''LightNovel/LogHorizon'', ''Manga/AkameGaKill'', and ''Literature/MardockScramble'' would work fine as additions to the Toonami lineup, and help both Toonami and Sentai Filmworks expand. Regardless, the relationship between Toonami and Sentai Filmworks, as well as the possibility of airing shows from the latter, remains unclear at this point (though comments from both parties point to the two being on good terms with each other, which at least disconfirms the "bad blood" rumors). Creator/{{Toonami}} has announced that they are airing ''Manga/AkameGaKill'' on their block, so it seems that they are establishing a business relationship for now.
*** Even after establishing a relationship with Creator/{{Toonami}} there were still some fans who weren't entirely on board with the decision. Some saw it as a new opportunity for Sentai to begin becoming more competitive with Creator/{{Funimation}} and start nabbing higher profile blockbuster anime. While for others the relationship showed potential for Sentai to give more love to catalog titles and air them on the block so they can gain new audiences. Though some were less enthusiastic about the relationship feeling that Sentai didn't have enough on their hands to provide consistent content for the block. It's not helped by the fact that as of 2016, Toonami's addition of ''Manga/HunterXHunter'' and ''Manga/JoJosBizarreAdventure'' have created two more slots for long-running anime, Creator/{{Funimation}} entered a partnership with {{Website/Crunchyroll}} to license more shows, and most of Sentai's 2016 licenses were sequels to shows they already had or obscure shows that Toonami would have no interest in airing.
** Sentai's tendency to preserve UsefulNotes/JapaneseHonorifics in their dubs can produce some polarizing reactions. On one hand, some purists prefer this since it keeps the script more intact, especially since it can difficult to dub something without said honorifics without losing some meaning in character dynamics or conversation (especially if the honorifics get directly referenced in-series). On the other hand, this makes it much harder for the dub to be taken seriously since english voice actors, especially ones newer in the industry, will be unfamiliar with using the honorifics, often leading to awkward or unnatural sounding recordings. Many of their recent dubs, even for series taking place in Japan, have forgone honorifics all-together, though.
** While fans have praised Sentai Filmworks selective dubbing policies (with some of it based on legal streaming views i.e. Crunchyroll, Hulu, and their own The Anime Network along with sub-only DVD sales) when it comes to dealing with niche titles, 2014 was the year where Sentai Filmworks started to make questionable decisions on ''what'' titles to dub. Supposedly popular anime titles and fan favorites such as ''LightNovel/GoldenTime'', ''LightNovel/ThePetGirlOfSakurasou'', ''Manga/{{Haikyuu}}'', ''LightNovel/MaoyuuMaouYuusha'', and ''Anime/CaptainEarth'' were given sub-only treatment while titles that were claimed to be near universally panned such as ''VisualNovel/DiabolikLovers'', ''[[VideoGame/AmnesiaOtome Amnesia]]'', and ''[[LightNovel/MahouSensou Magical Warfare]]'' with English dubs. However, many of these complaints may be the result of simple FandomRivalry, and fans of the supposed "marginalized" series that don't get dubs are just resentful that a series they personally disliked is getting a dub instead, and one does need to keep in mind that otome game adaptions have been doing very well lately, while sport series have bombed very badly in the past, with many not even having their English release finished, and especially for something as niche as the sport genre high streaming numbers don't necessarily equal good disc sales.
** Rereleasing the original ''LightNovel/VampireHunterD'' movie with a brand new english dub and ''not'' including the original english dub by Creator/StreamlinePictures. Some believe it's not that big of a loss due to the Streamline dub not aging well, while others think the Streamline dub should still be included, noting that their rereleases of ''Grave of the Fireflies'' and ''Appleseed'' still kept the original english dubs while also providing new ones.
** Sentai's handling of the ''{{Manga/Gintama}}'' license has been a common point of discussion among the company's followers as it's their most popular license. Despite the popularity and critical acclaim the franchise has received Sentai has hardly done anything with the license minus a series of bare bones DVD-only releases for the first 51 episodes of the first series and a test dub with the movie that was [[LoveItOrHateIt met to mixed reception]]. Some fans think that Sentai should give it much better treatment especially because Sentai has grown as a company since their initial release for it. It is generally agreed among supporters that Sentai should go back and re-release the series with an English dub with some going as far as to say that it should air on {{Creator/Toonami}}. Since ''Gintama'' is the only long-running shounen franchise Sentai has the license for many supporters say they should dub it to compete with {{Creator/Funimation}} and {{Creator/VizMedia}} and their licenses of ''Manga/OnePiece'', ''Manga/FairyTail'', ''{{Manga/Naruto}}'', and ''{{Manga/Bleach}}''. Supporters often use the dub for ''Manga/BoboboBoBoBobo'' as precedent to how a dub for '''Gintama'' can be handled. Others however think it is too risky a move for Sentai to dub the series. Since Sentai is a smaller company than Funimation and Viz Media they might not have the resources to dub the franchise, and some think dubbing ''Gintama'' is a bad idea in general due to the amount of Japanese culture jokes that would not translate well into English.
*** As of July 2016, this has been alleviated with Crunchyroll announcing that they'll be releasing the series on Blu-ray and DVD with an English dub. In addition the series is possibly going to air on Canadian television as it was approved for television by the CRTC. Now that Crunchyroll and Funimation have established a partnership with one another ''Gintama'' will be released on video by Funimation. As of early 2017, the English dub for season 3 was uploaded to Crunchyroll alongside the reveal that the Canada-based Ocean Studios was now providing their talent to the show. Though it has been revealed that Crunchyroll only has the license to the third and currently airing fourth season while Sentai still has the license to the episodes they released on DVD as evidenced by the listing on their website.
* CrackIsCheaper: Usually averts this trope. The price of their home video releases is proportionate to how much episodes the release has and if there is a dub or not and usually comes out to a fair price at launch. There's also the fact that their prices lower as a release gets older and their releases frequently on sale on their website and Rightstuf. Even their limited editions are on the less expensive end especially if they're in a sale and some fans even say the goodies in them is enough to justify the price.
* FandomRivalry: With Creator/{{Funimation}}
* GrowingTheBeard:
** Sentai Filmworks dubs in general fall into this even in comparison to their predecessor, Creator/ADVFilms. Many of their previous dubs were SoBadItsGood at worst and average at best. Their later dubs have better script writing and ADR Direction and even dropped the use of Japanese honorifics in their dubs. ''Manga/AkameGaKill'' and ''Manga/{{Parasyte}}'' dubs that aired on Creator/{{Toonami}} highlights the significant improvements of their dubbing when compared to their previous titles.
** In terms of home video releases Sentai was criticized for all of their releases being bare bones. Unlike releases by Creator/FUNimation, Creator/{{Aniplex}}, and Creator/NISAmerica their releases would often come with no on-disc extras minus the usual clean opening and ending animations and the packaging was very basic compared especially when compared to Aniplex and NISA who would package their releases in very nice art-boxes. However their limited edition release for ''LightNovel/ChuunibyouDemoKoiGaShitai'' showed that Sentai can deliver when it comes to limited edition releases. A lot of fans were pleased with the nice chipboard box the series came in, the fact that it included both the DVD and Blu-ray, the inclusion of on-disc extras, and even some limited edition goodies like Rikka's iconic eyepatch and a full color booklet. This would eventually influence Sentai to release limited editions of the same nature on a more frequent basis for their other popular properties such as ''LightNovel/NoGameNoLife'', ''Manga/AkameGaKill'', ''Manga/{{Parasyte}}'', ''LightNovel/BeyondTheBoundary'', and ''Manga/MonthlyGirlsNozakiKun''.
* InternetBackdraft: In [[ImageBoards some corners]] of the internet, they believe there are notorious for their occasional lazy dubbing jobs with casts made up of many no-name or very inexperienced voice-actors; an inability to consistently make proper translations when the English is literally on the video; putting obnoxious blurbs on the covers of some licenses that degenerate works into pure FanService; and allegations of shipping out ''blank discs''. (Obviously, that isn't true, and all Sentai releases always have the Japanese track with subtitles, and the presence of a dub does not prevent people from switching to the Japanese.)
** Their decision to license and dub ''VisualNovel/DiabolikLovers'', ''[[LightNovel/MahouSensou Magical Warfare]]'', and ''VideoGame/AmnesiaOtome'' and giving ''LightNovel/GoldenTime'', ''LightNovel/ThePetGirlOfSakurasou'', ''Anime/CaptainEarth'', ''MAnga/{{Haikyuu}}'', and ''LightNovel/MaoyuuMaouYuusha'' sub-only releases ''did not'' go over very well. Many of these complaints, however, are simply the result of one-sided FandomRivalry, as mentioned above, and said complainers typically know little about disc sales or how the English-language anime industry actually works.
* MemeticMutation: #[=SentaiNoticedMe=] [[labelnote:Explanation]]Pun from "Sempai noticed me." Sentai Filmworks is one of the most interactive anime licensing companies in North America in the internet social media; They will frequently directly reply to the fans' Facebook and Twitter posts, as well as favorite and retweet said posts or any posts aimed towards them that they seem to like. If your tweets or Facebook post is favorited, it's relatively common to reply with #[=sentainoticedme=] immediately when noticed.[[/labelnote]]
* SoBadItsGood: Some of their early dubs may fall into this category at worst. Their later ones have generally been either decent, good, or even great.
