Peaking at t = 0

Saw Ratatouille recently. Mildly amusing, but seemed too long. Is it just me, or does everyone feel that every neo-animated movie (i.e the post-Shrek era) is a disappointment? Finding Nemo, Monsters Inc, Ice Age and even the Shrek sequels have all been kinda ani-climactic. They are funny for about half an hour and then the writers have no clue where to take them. It's like the genre peaked at the very beginning. The only little burst of genius post-Shrek in animation movies has been a side-show. I refer of course to Scrat, the squirrel who can't seem to hold on to his acorn. By the way, if you haven't seen them yet, you should check out the 2 Oscar-nominated short films starring him.
