Is there anybody more badass than Arnold? While I admire the real life Arnold, the fictional Arnold on the screen in "Commando" and other films is one of, or they greatest action star ever. In "Commando" all he does is waste bad guys and drop one liners. Ahhh the one liner, such an important piece of action cinema. Arnold has more one liners than anyone else in Cinema, and "Commando" has a bulk of them.
The plot is simple. Arnold plays John Matrix, ex-commando, everlasting tough guy, and loving father to Alyssa Milano. Bad guys take Alyssa, Arnold goes after bad guys. The entire movie is just the following formula over and awesomely over again.
Arnold Meets Bad Guy + Arnold Wastes Bad Guy = One Liner
Sure that formula isn't going to win any Oscars but when it comes to satisfying the viewers, it's pretty hard to beat.
