Just as the title says, I truly dont understand why people hate this movie a lot, I think its fine and still really entertaining. Yes, from the 3 movies up to this point this one is the weakest, but that doesnt mean its bad. Yes, there are some moments in the story that feel weird, there are actually some plotpoints that are never adressed, it parodies itself a little bit too much, and etc. But the action is still pretty cool, the story while having its bunch of mistakes, its still very entertaining. I do hope more people appreciate it with the time.
