Broken Base: Long term Power Rangers fans aren't always happy when a person is brought into the franchise via HOPR over actually watching the show, due to said fans having a tendency to spout Linkara's opinions (something he's spoken out against). This ranges from Ninja Storm going from a well-liked season to being OK, Carter Grayson suddenly being a badass on par with Tommy Oliver, and Mystic Force also dropping in popularity.
Canon Fodder: While Lewis doesn't directly engage in this for the show overall due to it being a serious review show, he does do this for Power Rangers as a whole, with speculations about the existence of Scorpius's forces if Zordon's energy wave was suppose to "destroy all evil", the physics and length of a year for the Power Rangers universe, why Aliens came to be accepted on earth so easily in less than 20 years, where RJ got the morpher technology from, and other matters that crop up thanks to having a shared universe.
Dramatic Irony: Example of this applying to him instead of the show during his review on Mystic Force, where he comments that zord combination sequences look like "somebody took the Sentai footage and hit the fast forward button." Anybody that watched Magiranger would know that is more or less the case.
Growing the Beard: While fans generally disagree as to when HOPR officially hit its stride, most can agree that the first episode, covering Mighty Morphin Season 1, really wasn't that good, since it skipped Character Development for anyone who wasn't Tommy, Bulk, or Skull (not even giving analysis for the villains), skipped the season's originally intended finale ("Doomsday") barring a passing mention, and didn't even bring up characters like Titanus or Scorpina. He eventually did release a re-edited version of season 1 over a month after his video on Megaforce, and addressed many of these criticisms.
It's possible that his videos began to get really funny with his Turbo review, but he only really cut loose in his analysis and background research during In Space, and only kept growing it from there.
Other fans claim HOPR really came into its own at Lost Galaxy, as Linkara's Nostalgia Filter was finally officially off the table, and with the lack of Bulk and Skull, Linkara instead focused more time to individual Ranger analysis, which many fans thought was sorely lacking in his previous reviews.
Harsher in Hindsight: When he got to Billy leaving Zeo, he said he hasn't been able to find much information on why it happened, but he's heard it was because David Yost was hard to work with. Shortly afterwards, Yost finally did reveal why he left: he was constantly subjected to shocking verbal abuse over his homosexuality. In the next video to go up, Lewis confirmed that he'd seen the interview and will add it into the Zeo review in the future (which he did when he redid the video for YouTube, saying that he believes Yost).
In the wrapup for RPM he makes a meta joke about Ziggy and Dr K's actors getting married. They broke up in early 2016.
Every video is met with some comments calling him an idiot because his opinion is different from theirs, or because he has zero interest in Super Sentai other than for background information relevant to the adaptation (like the weirder parts of Turbo spawning from Carranger being a parody) or if people bug him enough about a certain part (The Legend War (note he did say that he watched the Legend War movie and agreed that it was awesome)).
He took steps to avoid it while reviewing Operation Overdrive, stating several times that he doesn't think less of anyone who likes the series and everything he's saying is just his own opinion.
While discussing the spoof film "Power/Rangers" in RPM, he makes sure to clearly say twice that it's perfectly fine if you liked it more than him.
In the Power Rangers in Space review, Linkara joked about the "anti-virus technique of hitting the monster with a sword". In a recent ad for a computer, which used video clips to explain its features, the anti-virus was demonstrated by... the original Megazord whacking Goldar over the head with a sword.
Speaking of his review for In Space, he notes that the promotional materials Saban had been given for Denji Sentai Megaranger showed a space-themed series...but the what they actually got was a video game- and device-themed show. If Saban had just waited 20 years, they would have gotten a series that was actually space themed.
He says a couple of the Rangers' suits from Jungle Fury look too much like track suits, apparently unaware that they actually were designed by a sports company in Juken Sentai Gekiranger.
The day after Linkara posted the first of the Remastered episodes of HoPR, Elizabeth Banks was announced to play Rita in the reboot movie. Likewise, production on the movie starts as he released the Remastered videos for season 3.
He has a Running Gag of discussing the various Ranger Super Modes and concluding that "At least it isn't glitter" because of the third season Metallic armor that was just the regular suits with a thick layer of color appropriate glitter on them (which were not only underwhelming but the suits are so brightly colored anyway you often couldn't tell it was different). The reboot movie featured close-ups of the new suits and helmets and comparisons to glittery rock candy came up.
Any time he complains about the Megaforce rangers getting too many Zords is this if you've seen Goseiger and know that there were Zords that weren't adapted - said zords are the Exotic Brothers, Mystic Brothers, and Datas Hypernote Exotic Brothers was only used once, and Datas Hyper wasn't used, since Tensou looks different from Datas; although it's never been revealed why Mystic Brothers wasn't used, as well as a ranger that wasn't adaptednote although said ranger would have required all-original footage, since Gosei Green, the ranger in question, only appeared in flashbacks, and even then, his costume was not usable, as it had been damaged during Goseiger's production.
In the Jungle Fury episode, Linkara complained that the Rhino Ranger didn't use the horn on his helmet as a weapon. Come Uchu Sentai Kyuranger, and the yellow ranger used his pointy visor as a weapon in the first episode.
"When's the next History of Power Rangers coming out?"Explanation Due to the series' lack of a schedule, it's a common question Linkara is asked by many friends and fellow reviewers in crossovers, and has since spread so that whenever anything TGWTG related is delayed or is taking its time coming out, Linkara's the one asked, even if he has no involvement in the project whatsoever.
Lampshaded during Nash's March Megastream, where every TGWTG contributer aside from Linkara that showed up was asked this. Everyone gave snarky replies.
More Popular Spin-off: For some, HOPR is in a lot more demand than Linkara's main video project, Atop the Fourth Wall. Even so, Linkara has said ATFW almost always takes priority over HOPR (helped by the fact he can only make HOPR episodes when new seasons have been released with their official DVDs).
Spiritual Successor: His Atop the Fourth Wall review of episodes 17-22 of Kyoryu Sentai Zyuranger (the episodes that were used to make one of Linkara's favorite arcs from Mighty Morphin, "Green With Evil") feels a lot like a mini-episode of History of Power Rangers. Linkara even has the chance to highlight the villains of this Zyuranger (something he neglected to do in Mighty Morphin), mentioning that Witch Bandora was actually kind of a badass in comparison to Rita Repulsa, and being able to actually acknowledge Lamie's existence, after forgetting to mention her US-counterpart Scorpina in his original HOPR review.
He also reviewed the first 5 episodes of Kaizoku Sentai Gokaiger from a Patreon request, same as Zyuranger, which allowed him to gain some insights on the differences and similarities between it and Super Megaforce and see why people like it as well as how it's far superior to Super Megaforce, as well that Super Megaforce copied Gokaiger wholesale for a lot of its episodes without very much reason or meaning behind the adapted episodes.
Values Dissonance: One of his biggest problems with Power Rangers Samurai is the lack of care in adapting Samurai Sentai Shinkenger's heavy focus on uniquely Japanese cultural values, such as Pillars of Moral Character and familial honor being put on children to drive them to inherit the family business, so to speak, for a more global perspective. It comes to a head during his discussion of Antonio's post-introductory episode, with him regarding Antonio as the most heroic of the Rangers, since he willingly chose to become a super hero of his own free will despite the risks and worked his ass off to do it, while the script is steeped in more-traditionally-Japanese notions of obligation and deference.
