I don't know if it's a flaw or I'm just missing something but I've seen the film twice now,and I still don't know where they got the mutagen to save Splinter.
Sacks had one can in the office.April took it after he got knocked out and told Shredder it's the last one.Shredder got it,takes the fall and it breaks on the ground.
So where did the mutagen to revive Splinter come from?
Oh man, you stopped way too soon with the questions.
How about why did Shredder and the Foot leave Raph (presumed dead) and Splinter (dying) in the sewers and only take the three turtles? They needed blood. Raph and Splinter's blood was still valuable whether they are alive or dead. But to prevent the movie from ending right then and there the villains left 40% of available mutagen lying in the sewers. Poor writing.
Then, shortly after that April calls Vernon from a pay phone. He answers and says, "OOOOO'Neil." Umm, how, what, huh? Was that her personal pay phone or something? How did he know who was calling him?
Also, when Sacks is in the lab trying to kill (I assume) April and Vernon he just stays by the desk and shoots in their general direction even though they are hiding. Why not just walk over and shoot them, because you know they are unarmed.
Then earlier in the film, April "stays up all night" making that stupid presentation for her boss, but NEVER, NOT ONE SINGLE TIME does she show good 'ole Whoopi the picture of the four, six-foot, ninja turtles that she took on her phone. But, after getting ****-canned, she drives over to the villain's mansion and the ONE AND ONLY thing she shows him is the freaking picture.
Those are just a few more execution issues.
Not to mention, Raph's speech at the end rang hollow considering the creative geniuses responsible for this steaming pile of **** failed to show any of the nonsense Raph was apparently apologizing for leading up to that scene. It was embarrassing to watch.
I know there are a few people running around trashing every other film in defense of this crap and it's gotten ridiculous. There really is no explaining any of what I just addressed (including the portion I quoted), because there is no explanation for them in the movie.
I apologize to Marvin and FrostBite, and anyone else who thought this movie was good. That is simply not true. It's not a matter of taste or personal opinion. This does not deserve a sequel.
