I disagree with comments that say that it was more vulgar than wedding crashers and american pie put together etc... I honestly don't know where these comments originated from. There was truly only one vulgar character (which is not necessarily a bad thing depending on your movie tastes), and that was Lou played by Rob Corddry. John Cusack was absolutely superb - and the movie is quite easy to enjoy if you were born in the 80's and remember a time when "Poison" was the most rockin' band around and hair a foot in length was the norm. The movie is quite witty if you can understand the wide array of 80's referances, but probably not a "gem" otherwise. As for minor characters, many other reviewers liked the one-armed bellhop - but I thought it was a pointless subplot in the film. I did however succumb to the charm of Collette Wolfe who played Kelly... she was part of an interesting albiet obvious subplot that added a lot of flavor to the show. I should also mention that if your looking for specifics on time travel - this is not your movie. There is no flux capacitor here ladies and gentelman: just an energy drink and a hot tub. All in all I give the movie an 8/10.
