The plot earns a 10/20 rating. The movie begins with Seth Rogen waiting for Jay Baruchel at an airport, and their reunion leads to a familiar scenario: they head back to Rogen’s place where he has gifts ready, followed by some recreational drug use. Rogen persuades Baruchel to accompany him to Franco's party so he can meet everyone. After introductions, they make a quick stop at a convenience store when strange lights begin appearing in the sky and the city seems to shift abruptly. They return to the party where almost all attendees suddenly fall into a large fiery chasm that has opened up outside. The actors then essentially spend the remainder of the film confined within the house, battling demons and attempting to reach heaven. While not particularly gripping, it provides some comedic moments. What I found most notable is their complete lack of effort to resolve the problem on Earth; even near the conclusion, their primary objective remains escaping the apocalypse by reaching 'heaven.' Rewatchability is rated 05/15. Despite having seen this film twice—once normally and once with commentary—I don't anticipate revisiting it unless I’m channel surfing and looking for something to watch. However, I would suggest experiencing it at least once. Although the movie is exaggerated and not intended to be taken seriously, you are likely to find yourself laughing a few times. The acting receives a 15/20 score. Because the actors essentially portray heightened versions of themselves, it functions quite well. The scenes featuring Michael Cera are particularly funny; at one point, he sneezes cocaine onto Christopher Mintz (who played McLovin in Superbad). No one seemed out of place, and even the supporting cast members like Rihanna and Mindy Kaling delivered satisfactory performances. Audio Production is given a 10/20. The soundtrack features music from artists such as the Backstreet Boys, Black Sabbath, Cypress Hill, Def Tones, Psy, and Whitney Houston. While these are recognizable names, it feels as though the songs were simply inserted randomly. The Backstreet Boys appear briefly at the end of the film when the characters are supposedly in heaven, celebrating. The special effects are competent but unremarkable. Visual Production is rated 15/20. Much of the film unfolds in a fictional Los Angeles and primarily takes place at James Franco’s house. The visual effects and post-production work are well executed. Listening to the commentary reveals that much of the filming actually occurred in New Orleans, inside an old coffee warehouse. Despite being largely confined to one location, it works effectively with the story.
