Meet the Spartans. Oh man, how did that get into cinemas? It just drove a dagger into the heart of silly movies (though to be fair, it was already coughing up a little blood).
Stitch: The movie comes pretty close. The original was quite charming and I really enjoyed it. The sequal was surprisingly short, the graphics weren't very good and it just retreaded old ground about 8 times. Not worthy of being in any decent movie library.
Off topic: I thought Sucker Punch was okay. Definitely weird, but could've be worse. I just have obscure tastes.
