This Is The EndI watched this, because it was compared to The World's End, as being a sort of USA equivalent. I can see why the comparison is made, but I find the characters in This Is The End a whole lot more irritating. Maybe that's because they're mostly USA actors playing caricatures (I hope!) of themselves. I don't really know many of them, and the ones I do know aren't terribly well known, at least not outside of the USA.
The World's End is a sort of Apocalyptic film, where it isn't actually the Apocalypse, whereas This Is The End does portray the Apocalypse. In both films, the characters manage to spend a lot of time complaining about things, which only complete idiots would do if the world was collapsing around them, which I suppose is part of the point of the films. I just found the USA characters to be way more annoying and petty than Simon Pegg et al in The World's End. Maybe that's just because both sets of characters are also somewhat cliched USA and English portrayals, and I relate to the Englishmen more.
On the other hand, I didn't pay much for the film, so I think I more or less got my money's worth out of it! Worth watching, it has its good points, but don't expect too much.
