Revenge of the Nerds and Revenge of the Nerds II reminds me of when teen comedy was funny, and not the tired routine that it has come to encompass in today's Hollywood machine. The jokes were funny, the characters were light-hearted, and your friends would always crack references from the script for the next week at school. Although they were filmed 3 years apart, they take place chronologically only 1 year apart. One can't help but to notice the big difference not only in clothing style but also in music. From Nerd-Punk (read: pseudo-Devo) to Nerd-Rap (read: pseudo-Beastie Boys), the difference is like night and day. But they can cook! I still catch myself singing phrases from the songs while at work or driving in my car.
Of all the different characters, Ogre and Booger are my favorites. The Nerd David versus a football playing Goliath. The crass humor these two contribute to the plot is just priceless! Conversely speaking, the "Snotty" character, Booger's Sensei from Part 2, was poorly executed and felt it wasn't used to the fullest. I would've enjoyed more scenes with Booger and Snotty.
All in all, I believe they're both solid films, despite the many parallels Part 2 runs to the original. I would give it a "5" rating if the DVD Bonus section had deleted scenes, bloopers, and a "making of" included. For those of us who grew up "Nerd", it's a priceless collection to add to your DVD library.
