I wanna say Lego Movie but my only gripes with it was the everything is awesome song, it made it alot more tougher to watch it with anyone older than 12
Oh and the forced romance, and the live action bit which was trying real hard to teach us morals, that moral being glue your Lego's
But the rest of it was funny and well done, especially the animation
I can't remember really horrible movies though, there's probably batches of dutch movies from when i was younger that are godawful
