I won't deny that there are some issues with the movie, but you're just pissing into the wind with the whole, "It's a bad movie, and you're wrong for believing otherwise!" bit. Good and bad are subjective. You didn't like it, so it makes it a bad movie to you
. I absolutely enjoyed the movie, and that makes it a good movie to me
. You can try to be objective as you want when pointing out what you feel are issues, but you're not going to convince anyone that it's a bad movie just because you say they are wrong.
