Amy! was itself an okay remake, and I think the hate it gets from fans of Amelie isn't entirely deserved. Seattle worked well enough in place of Paris, the director seemed to have a good grasp of what made the original so great, and the main actress wasn't terrible. But Amy's Wedding... Ugh, just ugh.
First off, they couldn't get the male lead to play the part, so they had to throw away the relationship that the first movie had built up, then they throw this new guy in our faces who is apparently her true love, and then they turn Amy into this airhead who can't do anything without Mr. Suave. If that wasn't enough, they have her spouting random, nonsensical lines as if that was enough to capture the quirky charm that made her so endearing in the original and the remake, as opposed to just making her seem like a mental patient of some kind.
Then there's the subplot where the hypochondriac goes on a road trip to stalk a male model. Probably the only funny part of the movie, or it would be if it weren't so creepy.
Oh, and an honorable mention to ET: The Return, which was just plain stupid from start to finish.
