I thought the fight scenes were starting to get tedious by the end, but I otherwise really enjoyed it.
The fights were the main thing that bugged me. One, how did this bunch of suburban schlubs know how to fight like Hong Kong action stars, and two, how did they still have the coordination to fight like that after seven pubs?
Also, the blanks were really fragile. Hard to see how their bodies were meant to be improvements on the human form. Although I guess they were a lot easier to repair.
