So, I checked out both of these movies in the last couple weeks. I have to say they are both worth watching, but they aim for two fairly different audiences. Pineapple Express is a HUGE pot/drug joke movie. The characters are well played and the story is entertaining. The relationship between the two main characters is hillarious though. Tropic Thunder on the other hand targets the action audience with gun fire, blood, and guts. This movie is packed full of top shelf actors 2 of which you will have trouble recognizing due to the great makeup work. The story is about actors trying to make a war movie and everything gets a little more real than expected. If you like quotable movies this is it. Line after line in this movie is hillarious. Either way, both movies are worth seeing. If I had to choose one to see on the big screen though it would be Tropic Thunder.
