REVENGE OF THE NERDS II: NERDS IN PARADISE (1987)
Revenge of the Nerds II tells the story of the Tri-Lambs, who are invited to a national fraternity conference in Florida, but are not welcomed by their foes, the Alpha Betas. Most of the original cast is back in action for the sequel, and even a few surprises like an Alpha-Beta turning Tri-Lamb (this was sort of homaged in Accepted). Like the first film, the Tri-Lambs must rise against and prevail.
I was introduced to the Revenge of the Nerds series at a young age by my uncle. I didn't get most of the jokes but I knew a good comedy when I saw it. But when I saw the sequel, my first reaction was just a great big yawn. There really wasn't anything new, except for the lovely Courtney Thorne-Smith, who I absolutely fell in love with in Summer School.
If you're a completionist like me, then see it. Otherwise, well, do what you want.
