Beyond that, I'd have liked more background on Casey Jones. The little we got was good, just more would have rounded his character out more instead of him just popping up out of thin air like that. Why is he a vigilante? Nobody knows...
There was a scene cut from the final release that dealt with this. Casey was getting fed up with watching reports of criminals getting away that he decided to become a vigilante. Also, remember that conversation he had with April before they all went back to New York? April talked about him playing professionally and Casey said "before I was injured."
If that cut scene of Casey watching TV was included, I think the intention was to give people the idea that Casey was a professional athlete, probably hockey, who got injured and was without purpose until he decided to become a vigilante.
Winters' "change of heart" was a little sudden. Early in the film while talking to Karai and the Generals he seemed pleased at the opportunity to take over the world with his army of darkness. Then all of sudden he just wants to die in peace? There was very little explanation for this sudden change.
I've got to disagree with this. I thought they were hinting at Winters' change of heart right from the beginning. The fact that his actions turned his "family" to stone and the fact that he was trying to gather the monsters together again. The entire time watching it, I was actually thinking to myself, "wait a minute... why is Winters gathering the monsters if he already has immortality? Is he really the bad guy?" I think if you watch it again, you'll find there were enough hints showing that Winters wasn't actually the villain of the movie.
The 13 monsters portion of the storyline was pretty nonsensical. Why 13 anyway? They only showed maybe 7 or 8 in the film as it was. I still don't see how destroying the monsters would serve to de-stonify the generals and finally kill Winters.
Destroying the monsters didn't matter. What did matter was sending the monsters back to their dimension. That would reverse the curse. The curse was that by releasing the monsters, immortality was gained. However, the generals only gained immortality by being immortalized in stone. Winters gained true immortality, but over the centuries discovered that immortality wasn't all it's cracked up to be. By breaking the curse, i.e. returning the monsters to their dimension, that meant the generals and Winters would lose their immortality -- thus, they would die. I thought they explained this pretty well in the film, especially when Winters talks to one of the generals who says, "but if we break the curse then we won't be immortal."
How is it that they couldn't find the biggest, meanest, and most destructive monster for so long? Don't you think someone would've noticed the dinosaur like thing running around destroying the city?
I agree with this one. I thought it was a bit convenient that all thirteen monsters were located in New York. My theory is that they were drawn to the location of the portal, but there should have really been something stated in the movie to clarify this. Guess it just has to be chalked up to coincidental comic book luck.
However, now that I think about it, Winters
did tell Karai that he was expecting some friends to arrive...
