“The Night Before” (** out of four) was a middling comedy about three lifelong friends (Joseph Gordon Levitt, Seth Rogen, and Anthony Mackie) who reunite on Christmas Eve looking to find the Holy Grail of Christmas parties. By the admittedly very low standards of Seth Rogen comedies who I am not a fan of, this isn’t bad and has some laughs and is a throwback to “Half Baked” and Chech and Chong movies. Still, it’s awfully thin stuff and gets too repetitive and dumb after a while. Gordon Levitt and Mackie show off some of their comic skills but viewers will likely forget this by the night afterwards.
