There were many parts I liked but it was hard to get into the world the movie makers were trying to bring us into because of stuff like automatic crossbows that could rapid fire, horses that break down doors, arrows leaving bullet holes in stone walls, arrows used as signal flares, arrows used to blow open locks... I kept trying to get into it, I really wanted to have fun, but the weapons were so over the top that it lost me. Watching people get killed with spaghetti from a noodle gun would have had the same emotional effect on me.
The film had me laughing a lot and the effects were impressive. It had plenty of good parts. To enjoy it though, you'd need to be somebody who can ignore or not care about inaccuracies.
