Quite surprised that one of the films that I picked made it this far.
Finding Nemo is certainly a damn good film, but I doubt that it will be as popular as Jurassic Park years after it's release. I'll give Finding Nemo it's due, but it is missing many of the things that make Jurassic Park better in my opinion; such as an epic music line.
I cannot remember any music from FN but I do remember the JP music quite well, and every time I listen to it I get a cold chill of something amazing. One other thing I find remarkable about JP is that the special effects are so good for a film of it's era, possibly quite revolutionary for it's time, while FN is just the same as in any other recent Pixar production.
JP has two or three (?) sequels while FN doesn't, though that is probably just because it isn't a story you can really continue (unexpected sequels thread anyone?). Also FN is missing a scene of a t-rex fighting raptors whilst a banner with "Jurassic Park" written on it falls down.
Finally a bone to pick with FN is that it is supposed to get across the message that keeping wild animals, particularly tropical fish, isn't that great (but not for the reasons it depicts). This is all fine in itself, however it did cause a rise in demand for clownfish - a very hard animal to keep alive - which is the total opposite of what message it was trying to get across. Plus it means that children always shout "Nemo!" whenever they spot any member of the Amphiprioninae subfamily.
EDIT: This post is quite long... Is it wrong that every time I wrote FN I thought of a Belgian gun manufacture?
