In my humble opinion..
It really helped the score that the movie was about Team Fortress 2 (great game! Seen the latest Sniper movie?).
Just like the first one, the dialogue was boring and there was nothing clever about it. The only decent line is 'ONLY YOU DIE'. But the way it was delivered kinda ruined it. (Sorry, I know voice acting is hard).
The action was a step down from 'Meet the Pyro' which I thought was more enjoyable (the action part). Seeing the Spy stab, stab, stab wasn't all that interesting.
Still, props for staying true to the TF2 graphic, but I gotta ask you: Why using ugly strokes to draw the mouth when everything else is clean and nice to look at?
