History YMMV / ThomasAndFriendsAllEnginesGo

* AndYouThoughtItWouldFail: The series was such a departure from almost everything that came before it that fans were revolted to the point that they were convinced the series would flop. Once the official premiere date came and went, however, ''All Engines Go'' was astonishingly successful, as not only did it win over its intended audience, but the "flaws" brought up by the older fanbase were mostly superficial, as despite the series falling victim to the same shortcomings as most similarly despised contemporaries, the dialogue was relatively sophisticated for what it had as the target audience, while the animation was more higher quality than most modern 2D animated shows, using traditional animation over MediaNotes/AdobeFlash or Media/ToonBoom. Most of the show's detractors have now also toned down their complaints, as aside from extreme exceptions which have quickly become reported, many slights against the show are now relatively mild and restrained.

* SoOkayItsAverage: While the show has received negative backlash from fans of ''Literature/TheRailwaySeries'' and ''WesternAnimation/ThomasAndFriends'' for the many changes made to the tone, cast and setting, in spite of the backlash, reception towards the first few episodes has leaned towards this direction, with many admitting that the show isn't bad when viewed on its own merits and arguing that if it wasn't associated with the ''Thomas & Friends'' brand and was its own thing (or was just a spin-off or a series of Website/YouTube shorts rather than a replacement for the original series), it could have been an alright (if generic) kids show. As such, some opinions of the show relaxed when it was revealed that it was in fact a separate spin-off of the Thomas branch rather than a continuation of the original series.

* TheyChangedItNowItSucks: Ooooh boy, to say fans and parents were cross at Mattel is a massive understatement. The initial announcement and the first images of the show were met with severe backlash from both the fandom and parents, a backlash that only grew as more details about the show were revealed due to it being a massive departure from what Thomas was known for to the point of being almost Thomas InNameOnly. Several parents have also claimed that their children (aka, the show's target demographic) are not fond of the show either. In particular, autistic fans feel betrayed by the reboot because it goes against everything the original stood for; being a relatively calm and low-key series amidst a sea of rapid-fire ones. The calmness and simplicity made it very popular with autistic people, and now Mattel has taken that all away. By the end of the second season, most of these complaints have either died down or lessened in intensity, though aside from a small few who treat it as an insult to the franchise, most of the fanbase has learned to accept the new series as it is.

* JustHereForGodzilla: Creator/NeilCrone [[RoleReprise returning as the voice of Gordon]] after over ''20 years'' has been cited by some fans as their reason for watching.

* AndYouThoughtItWouldFail: The series was ''such'' a departure from almost ''everything'' that came before it that fans were ''revolted'' to the point that they were ''convinced'' the series would flop. Once the official premiere date came and went, however, ''All Engines Go'' was ''astonishingly'' successful, as not only did it win over its intended audience, but the "flaws" brought up by the older fanbase were ''mostly'' superficial, as despite the series falling victim to the same shortcomings as most similarly despised contemporaries, the dialogue was relatively sophisticated for what it had as the target audience, while the animation was more higher quality than most modern 2D animated shows, using traditional animation over flash or toon boom. Most of the show's detractors have now also toned down their complaints, as aside from extreme exceptions which have quickly become reported, many slights against the show are now relatively mild and restrained.
* SugarWiki/AwesomeMusic: While the reboot's usage of musical numbers has received a mixed response, the songs themselves are pretty catchy when taken in context. And then there's the fact that ''every'' song has an extended album release.

* ItsPopularNowItSucks: A ''LOT'' of fans felt this way when the episodes finally aired, but while most fans were relatively respectable about the subject, an alarming number of fans weren't as courteous and ''virulently'' attacked ''anyone'' who was reported to have liked the series, even going so far as to go after ''preschool children'', the reboot's ''intended primary audience''. Needless to say, this behavior was heavily frowned upon by the more respectable members of the fanbase, a number of whom were actually parents with children themselves. As such, they heavily discourage this and similar methods of expressing distaste. Fortunately, the vast majority of these cases have died down a year later, and aside from a few extreme exceptions most criticisms of the show in the present day are much more mild, diplomatic, and refrained. Fans have also become much more vigilant in reporting fans who do not respect others for liking the reboot and have become more conscious of promoting a fair and all-encompassing atmosphere for the fanbase.

* {{Moe}}: While ''heavily'' criticized by older fans upon the full reveal, all of the characters were either portrayed as children or given modified designs to appear cuter. This works to a limited extent, but Percy, Bruno, and Sandy are standout examples for the series.
* NightmareFuel: Thomas's forced attempts to smile in "Blue Engine Blues". Kiss any peaceful sleep of yours goodbye.

* OvershadowedByControversy: While not as bad as ''WesternAnimation/TeenTitansGo'', it's rare to find any written feedback or commentary about the series that actually ''praises'' it, with most of the fan comments being borderline ''hate speech'' before content creators began deleting the most overzealous and aggressive ones. In general, it's near-''impossible'' to talk about ''All Engines Go'' with a ''Thomas'' fan without said fan adding at least ''one'' comment of displeasure.

* TaintedByThePreview: The first promo images for the reboot riled up fans so bad that a good number of them began ''sniping'' at those who claimed to like it.

* TheyCopiedItSoItSucks: This is one of the biggest reasons why fans of the books and the original series despise the show, as many have criticized the show (and by extension Creator/{{Mattel}}) of stripping away everything that made Thomas beloved and unique in the first place, in favor of replicating and competing with modernized and generic MerchandiseDriven kids shows such as ''WesternAnimation/PawPatrol'' and especially ''{{WesternAnimation/Chuggington}}''.

** Unexpected actor in this case; when Toby's first episode aired with the Canadian vocals, fans were shocked to find he was voiced by ''Creator/EdwardGlen'', who last voiced Thomas himself in ''Thomas and the Magic Railroad''.
** The appearance of ''Winston'' in the third season trailer came as a big surprise for many, especially considering that Winston had suffered a ''severe'' case of DemotedToExtra in the original series and that Emily was seen as Sir Topham Hatt's chauffeur in the reboot.
