Oh, puhleeze.
It wasn't really terrible. It was about the same as Transformers or other action-special effects films. Star Trek comes to mind. Terminator. Predator vs. Aliens. Others.
LOL. It won't win any oscar nominations (unless in special effects)...so it certainly isn't great for plot or character development. It's not an A movie. It is what it is.
I heard that it was terrible before I went. I have a friend who even said that it was so bad, that he would pay people not to go. Ha. But the kids wanted to go (11 and 15yrs). So I took them. They both loved it (rare) and I enjoyed it too.
Anyway, it clearly is not everyone's cup of tea. And I would not ever argue that it is a great movie. But it is far from terrible. Particularly given for the type of movie that it is.
But I went. And it was just fin.
