Friday the 13th
Friday Part 5 gets a lot of slack in the horror community. Probably because it isn't the "true" Jason, just an imposter. But if we can get over that little tidbit, you'll find a movie with spectacular kills, the unforgettable Tommy Jarvis and, most importantly, lots of wonderful 80's horror nudity. We've got Rebecca Wood (it's SHOWTIME!), Deborah Vorhees (also known as Debisue Vorhees), and Julliette Cummins.
After the somewhat lame Friday the 13th Part III, Part IV came out swingin'! Not only do we get Corey Feldman and Crispin Glover, but we get more skinny dipping with twins, naked romps in the woods and Jason starting to really come into his own as the slasher we all know and love. Overall, Part IV is one of the best of the series, and the plethora of nudity certainly helps that cause.
You'd be forgiven for not liking Friday the 13th part III. Because it was originally shot for 3D screens, some of the shots that may have looked good in 3D are distractingly bad. The biker gang subplot went nowhere. The kills were uninspired. This was the movie when Jason got his mask, but is otherwise a pretty forgettable installment. Oh, and don't forget the "blink and you'll miss it" nudity from the beautiful Tracie Savage.
