Has Seth Rogen ever been in a bad movie?

Rating: 9/10 (22 June 2013)

"This is the End" is a laugh riot. Has Seth Rogen ever been in a bad movie? His lowest rated movie per RottenTomatoes is "The Watch" (16%), but I thought that was a pretty funny and entertaining movie. I think "The Green Hornet" is the limpest of the bunch. If you are offended by that adjective, you definitely should NOT watch this movie as there are more male body/sex/potty jokes than I've seen in any other movie in my lifetime (and I am old enough to remember Porky's).
At face value, it seems like it would be pretty hard to screw this movie up with Seth Rogen, James Franco, Jonah Hill, Danny McBride, Michael Cera and a dozen others playing themselves during the "Apocalypse." Even Rihanna and Harry Potter's Emma-freaking-Watson have extended cameos. There is one cameo that is so absurd and crazy that it would be a major spoiler to reveal it.
Speaking of spoiler alerts, you'd think that the cause of the Apocalypse wouldn't be revealed, but that hasn't been the case with one reviewer mentioning that it as a literal interpretation of the Bible's Book of Revelations. You're at least 45 minutes into the movie before they reveal what is really happening (unless you are, or were, raised Catholic. Then you get it pretty early on).
Yeah, it's also a riff on the egocentricity of Hollywood celebrities, but who really cares unless you are an avid reader of TMZ or Perez Hilton. The real brilliance is in the dialogue, a ton of which has to be ad-lib/improv. There are so many jokes in this movie told in the context of the story it would fill a TV comedy series for multiple seasons.
This is a two-hour comedy movie. Do they make any comedy movie that long? I just hope it has a "Lord of the Rings" style Extended Edition on DVD.
