Found this movie totally boring. The only moments that I felt connected to the movie or the characters at all were the forced bits of nostalgia sprinkled about the movie. Over the top blood and violence aren't the only things you need for a good story. You need to tell a story that connects your audience to the characters so that we root for them.
The story in this movie meanders so much and has so many characters that really don't go anywhere from the beginning of the movie to the end. Plot threads start and then fizzle out going nowhere. And it builds to a climax that resolves nothing. A complete waste of time.
