These days 3D movies are all the rage with numerous titles coming out in 3D on the big screen and 3D TV's making their appearances in homes across America. Personally I don't see what the fuss is all about. With the exception of a few releases such as Avatar and U2's 3D concert film, the effect is mostly wasted and adds very little to the experience of watching the movie.
Now let's travel back to 1982 when Friday the 13th waded into the 3D pool and the effect was a novelty. I saw it in the theater and remember thinking how cheesy the 3D effect was. It was reduced to a sequence of gratuitous "cheap shots" where things jumped off the screen and into your lap in order to give you a scare. Ho-hum. Even watching it now in 2D the viewer can tell where the effect kicked in and can see it adds absolutely nothing to the experience of watching the film.
Part 3 is the weakest of the franchise so far. The 3D effect was enough to get people out to the theater but, unfortunately, they were treated to very little else. The acting is the weakest of the first three films by far. I found myself caring very little for what happened to anyone in this film. Furthermore, the plot is basically non-existent. It's just a series of mindless killings that aren't particularly inventive or interesting.
The biggest problem Part 3 has is continuity. In the intro montage we have "Jason the small" with a pillow case over his head and a thirst for vengeance for the beheadding of his mother. Then, all of a sudden, we have "Jason the large" who must have taken mega-doses of growth hormones between Part 2 and 3. We also have the introduction of the iconic hockey mask and machete more than half way through the film. Yet there is no creative explanation for why Jason chose these items. He simply picked them up off the ground between killings. Puh-lease. Don't insult your audience. We needed more than that!
Part 3 feels like lazy filmmaking, which I hate. The subject matter is already wearing thin and doesn't really get any better in the sequels that would follow it. The things that made Part 1 great are simply not present in Part 3. Too bad everyone decided that making lots of cash was more important than artistic integrity. This one belong on the bottom of Crystal Lake!
