It was OK
It was pretty good (about as good as stick death can get, I guess), but I think it would have been very cool to have more sticks on the screen at once - it seemd like it was almost always 1 on 1 things, and occasionally there might be four guys on screen (all getting blown away at the same time, of course). Maybe have 10 guys on 2 teams blasting at each other with machine guns all at the same time. It would make the movie seem much faster and much more intense, I think.
The movie has OK sound and it was well synchronized. Also, kudos for bringing the size down while still making the movie longer than in Battlefield I.
Overall, it was good, but not great. This whole stick death thing can only go so far, IMO.
