These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: Teenage Mutant Ninja Turtles: Turtles in Time
It's Easy, so It Sucks: The SNES port for some people. The gameplay is slower, bosses and enemies are easier than their arcade versions and Sewer Surfin and Neon Night Riders became bonus rounds.
It's Hard, so It Sucks: The Genesis port, Hyperstone Heist, can be this for some. While there aren't as many levels (there's five) compared to Turtles In Time, the stages are longer, enemies move faster, and attack more aggressively.
It's the Same, Now It Sucks: Those who are aware of the Arcade version say this about the remake, which was a bit too accurate to the arcade, and didn't have many features from the somewhat more popular SNES version.
This is how some feel about Hyperstone Heist, since aside from adding a run button, there is not much else. There are some new areas, but everything else is a re-skin of stages seen in the Arcade/SNES counterparts. Though the environments have more details and faster game play compared to the SNES.
Mis-blamed: The fans say that the game "Removed" several features that made the game good, like Bebop and Rocksteady, the Technodrome, and Super Shredder... When they're talking about the SNES version, which expanded upon the arcade game.
Narm Charm: Shredder, in the versions he actually says: "Turtle Soup, my favorite!" would probably be ridiculously funny, if the actor didn't sound so awesome.
Polished Port: The SNES version added an extra level, extra bosses (not to mention changing some of the original, adding mainstays Bebop and Rocksteady and Slash) and a few new resources (time-trial, two-player versus). It was so improved many complained Reshelled just copied the arcade.
That One Boss: The SNES version replaced the cement man, a minor monster that only briefly appeared on the show, with Slash. Unfortunately, he's the hardest boss on the SNES version for many reasons. He is a Lightning Bruiser that's immune to frontal attacks and he can counter with a rolling attack that deals a few bars of energy when he Turns Red.
Then again in co-op he easily becomes ridiculously simple to beat. Who can say SLASH PING PONG?
Slash is also vulnerable from behind, so it helps to sneak behind him as he attacks and then hit him from there. Just about every boss is easy when you know how to beat them no matter what difficulty, although Krang in his flying saucer can be a little tricky.
They did, however, completely change the soundtrack, which many fans (whether it's of the arcade or the SNES version) are bitter about.
Fans of the arcade version didn't really like Sewer Surfin' and Neon Night Riders becoming bonus stages. Especially since they're shorter, enemies die in one hit and you can easily avoid hitting anyone until the end.
Fans of the Arcade or SNES version do not like the fact that the Genesis port lacks the throw-the-foot-ninja at the screen maneuver.
