Blowing up the BMW with a shotgun lol
It looked like a spas 12 shotgun, and take or leave the terrible acting (Bathroom scene, watch Max's face, looks like something out of Team America with the puppets) but he fires at the BMW and i blows up as if it had C4 under it or something.
Even if we concede that the tank was metal, which it isn't, it is plastic, then there would still need to be a large enough spark, and just the perfect air fuel mix to ignite, and even then the whole thing wouldn't go flying up as it hit by a rocket or something.
Just made me laugh is all, this movie did seem like it was the 'real' team america or something with the acting/special effects, not that i didn't enjoy it! it was very entertaining :D
