If you're expecting a variation of Polar Express, I hate to break it to you, but Pineapple Express is not a movie about a train to Hawaii. It is however, a comedy worth your theatre dollar, including popcorn.

The premise behind the movie is that Seth Rogen witnesses a murder committed by cop and a drug lord, and thus is on the run. Along the way Rogen is joined by his pot dealer, played by James Franco, and they enter a number of humorous situations, from living in the woods to a cop-car chase, and an epic fight in a secret abandoned government testing facility.

The mix of action-comedy in Pineapple Express is similar to that in spoof movies and comedy franchises such as Austin Powers, where it mocks the genre, but is also compelling in its own right. The scenes were well-choreographed and even brought some empathetic pain to the audience, and the requisite car-chase scene was filled with laughs and stunts.

If there was one downside to the movie it was probably the semi-romance storyline introduced with Rogen's teenage girlfriend (she is 18, at least). After Rogen forces her family to flee their household, they are forgotten, leaving you wondering just where they went and what they did. Except for the comedy it brought in, Pineapple Express would be better-off without the added storyline. Also, if you're not wild about drug references then you should definitely skip this movie, since it's really only about two things: comedy and weed (the title of the movie gets its moniker from a "strain" of weed named Pineapple Express).

However, those are only minor glitches in the otherwise enjoyable Pineapple Express. While it is probably not going to win any Oscars, and with all the great movies that came out this summer it may get lost in the shuffle, Pineapple Expres is satisfactorily funny that you won't feel as though you've wasted your money. If you have the extra 2 hours to spare, I'd recommend you see it.
