History YMMV / TurtlesForever

* VillainDecay:
** This Trope was inverted for threats from the 2003 such as Hun, who [[spoiler:mutated into a Turtle monster, while this condition isn't exactly ''liked'', he actually becomes much more powerful to the point where he can no-sell most physical attacks and the only way the Turtles can put a stop to him is by tricking him into running into environmental hazards.]]
** Played ''very'' straight with Shredder and Krang, who went from goofy but somewhat menacing in the '87 show to {{Ineffectual Sympathetic Villain}}s here. Justified in that they're nothing compared to [[EvilerThanThou the Utrom Shredder]]. Although given that they had access to the Super Technodrome after the end and were still planning to use ''a giggle ray'' to attack kinda implied that they're still decayed. To their credit they did realize the threat the Ch'rell possessed and tried to contain him and dissect him for his secrets, only being stopped thanks to Karai invading their base.

* BrokenBase: The movie's treatment of the 1987-verse is heavily divisive among the fandom. While some saw the '87 turtles exaggerated characterizations as tongue-in-cheek that helped extenuate how out of their element they were when thrown into unfamiliar worlds, as well as the message that every group of turtles is valid regardless of their personality. Others, (particularly fans of the 1987 series) hated how it made the '87 turtles look like fools, feeling like it only served to make the '03 turtles look good and an insult to the old series. Ironically one of the criticisms levied at the movie is that the attitudes of the '03 turtles to said counterparts made them rather unlikeable and sapped some of the enjoyment out of the movie since it seem like they were working with their counterparts in a begrudging manner. '03 Raph in particular never seeming to ease up on his complaints about them bringing him to near [[TheScrappy Scrappy territory]] for the movie.

* {{Misblamed}}: Most assume the writers essentially did CriticalResearchFailure when it come to the 87 turtles explaining why their personalities don't match up with their show. According to J's Reviews, this is partially true, in truth they wanted to look into more of the original show but only had the pilot to go off of and nothing else during the movie's production, because of that they mostly based the '87 personalities more on the tone to help with their characters. Likewise Peter Laird was the one giving the approval of concepts for the movie and waved this idea through. Considering Peter was known for being displeased how LighterAndSofter the original series was, it wouldn't be out of place to say this may have been an intentional move on his part (the praise most of the '03 cast get from their '87 one not exactly helping). Though likely could've been an oversight as well.

* AuthorsSavingThrow: After the unpopular change in art styles for the 2003 series for the ''Back to the Sewers'' season, this film switches the turtles back to their ''Fast Forward'' designs, with no pupils in sight.

* {{Fanon}}: There's a little bit of fan speculation that due to meeting their more serious 2003 and Mirage counterparts, the 80s Turtles decided to up the ante and [[Recap/TeenTitansGoS2E32LetsGetSerious become more serious]] characters. And thus, ''Turtles Forever'' was, in a way, responsible for [[DarkerAndEdgier the "Red Sky" seasons]] of the first Ninja Turtles show.

-->[[spoiler: Hun]]: [[spoiler: Yes. Mutation, it's a real ''horror show''.]]

** Most didn't have too much problem with the movie, but the treatment of the '87 cast did hamper some enjoyment. A criticism of most is that they don't mind if they want to pay homage to the sillier aspects of their show, but the [[UpToEleven overcrank]] just to differentiate the two turtles doesn't really do the crossover justice when one side can't compliment the other and ''especially'' when you make the other side too foolish or weak to be helpful (which in turn is just a big no-no for crossovers in general). As such many have cited this makes the movie feel uneven as the writers couldn't seem to balance keeping the '87 characters light-hearted nature up with their competence.

* MoralEventHorizon: 2003 Shredder does it again, as he [[spoiler:callously attempts to murder the Turtles by using them to pinpoint Turtle Prime. Granted, he's tried to kill them hundreds of times before...but not while Splinter was ''watching them die'', yes, the other Shredders have attempted this, but there was no real sign of a DeusExMachina, ChekhovsGun, or really anything this time that could save them except somebody from the outside, this is what gets Karai to ''finally'' switch sides for good.]]

** While '03 April and Casey get to help out a bit in the movie, many older fans were disappointed the 80s April was regulated to a wordless cameo and a joke one at that. Likewise Irma and Vernon only get quick cameos as well, robbing them of any interaction with the '03 cast too.

* SugarWiki/AwesomeAnimation: While the characterization was heavily questioned, most fans do agree the animation for the 80s Turtles and their villains was pretty spot on, duplicating their look perfectly. Likely were more than happy to see the Mirage turtles finally have full on movement too and representing their gritty aesthetic.

** 2003 Shredder's death. [[AssholeVictim Sure he did had it coming]] but watching him get shredded by his own device while [[DeathWail he's screaming in clear pain]] is a pretty dark way to end him. Though granted, not the first time he suffered a grisly death if you remember "Same as it Never Was'' where he got ''drilled in the face'' by Donatello.

* CatharsisFactor: Ch'rell being obliterated by his own device, at the hands of ''Bebop and Rocksteady'', of all people, is definitely this for all the horrible things he's done throughout the entire 2003 series.

** Played ''very'' straight with Shredder and Krang, who went from goofy but somewhat menacing in the '87 show to {{Ineffectual Sympathetic Villain}}s here. Justified in that they're nothing compared to [[EvilerThanThou the Utrom Shredder]]. Although given that they had access to the Super Technodrome after the end and were still planning to use ''a giggle ray'' to attack kinda implied that they're still decayed.

* FunnyAneurysmMoment: "Another fine mess you've gotten us into." Krang, you don't know how accurate you are.

* WTHCastingAgency: While most people know that the original 1987 actors couldn't reprise their roles for legal reasons, some thought the new actors neither sounded close enough nor acted in spirit to the characters with the exception of Sebastian Arcelus as 1987 Raphael.
