I'm still amazed at what people will call 'crude' and what they will not. Not that Jason Segel's full frontal was necessary, but why is it that we are so uncomfortable with it as a society? Pre-film that was the biggest news about this movie. And really it's not.
I didn't expect Jason Segel to be able to carry this film, but amazing enough, he did. How nice to see a leading man who isn't a sculpted Adonis, but instead a guy who represents most of us. It took some tremendous guts for Segel to go au natural considering the amount of weight we as a crazy society put on looks. And he held his own well. Whereas I'm sure all females look like Kristen Bell and the utterly stunning Mila Kunis.
For my $10, this movie entertainment me for two hours. It is adorable, silly at times, but fun nonetheless. The emotional aspect is something we can all identify with. No, it doesn't carry the punch of some of the Apatow films, but it also didn't simply rely on the easy laugh as SuperBad and Knocked Up did far too often with all crude humor all the time. The humor is more subtle, the way the characters go about their business is not nearly as predictable as one might think and the story is what you'd expect from a romantic comedy.
It's sad that Apatow's crew felt they needed 'shock value' in this film to make it relevant or funny. Even more sad is that full frontal on a male is considered "shock value" when death and violence are not. There are some adult moments in the film, but almost nothing your teen hasn't encountered on their own. The R rating is simply for language and the fact we abhor nudity more than someone chopping another's head off.
You'll enjoy this film for what it is, and if you're looking for a good date movie, you've found it.
