As usual he gets exposed...in more ways than one...and must redeem himself. And, as usual, others are affected by his affable schemes. In this case it is the same jerks you have seen before, the Seth Rogen stock characters. You know...the High School kids who want to be cool but never quite made it? The ones who want to collect Yu-Gi-Oh cards and be well-liked by the girls...and somehow, in every Rogen flick, attain it.
I think there should be something like the "Seth Rogen Law" which is something along the lines of, "The hotness of the girl gotten is inversely proportional to (nerd factor x loser traits)". For instance, in the real world someone as hot as Katherine Heigl who had a great job would, theoretically, not hook up with a guy whose life revolved around porn and getting stoned, who thought a job was getting high and playing ping pong and who had no redeeming social qualities. Yet in Knocked Up (2007) that couple is a foregone conclusion. In Drillbit Taylor the homeless, AWOL scammer Drillbit Alamo Taylor he is going to end up with mega-hot schoolteacher Barbara (Beth Littleford).
Along the way there is a fresh take (?) on the nerds versus bullies paradigm as Eminem clone Filkins (Alex Frost) and his running buddy are humiliated in a rap battle by Ryan (Troy Gentile) and then beaten in the climactic fist fight by Ryan, stunt-stick figure Wade (Nate Hartley) and super-geek Emmit (David Dorfman).
