Yeah, it's THAT bad.
I will admit that there were a couple of plot twists which I found to be a nice surprise, but overall it was a predictable and unfunny movie. And I ABSOLUTELY hate the tired, overused, boring and very ridiculous premise that "despite mankind's flaws, humanity is worth saving even at the cost of BILLIONS of lives." That's a propaganda piece that's been spewed across hundreds of genres that nobody believes anymore. It's a tired plot point that makes the ending all the more predictable. This film goes straight to the bottom of the Marvel pile -- yup, even underneath the second Thor movie.
