I think people just doesn't get this movie.

For me, this was the best of the trilogy. Why? Because it is the most clever of them all. The first was just an overhyped "OK" movie, and the second one was pretty bad. They both had a serious tone, yet it always seemed the director was messing with everybody with those ridiculous taglines etc. And here we finally go full circle in this franchise. All seriousness is stripped away and it's just a full out onslaught of cheesyness, jabs at critics, jabs at the franchise itself, jabs at fans, jabs at the actors (the main actors here are the same as in the previous two movies but as other characters) and the result is just downright hilarious. Dieter Laser is very good and very funny here. For some good measure we also have some porn acting (I mean one of the main characters is actually a porn star).

And now add the grossness from the first two films and multiply it by two and shove that into the film. The result is pretty spectacular. The movie is much more gross than the previous ones and yet you find yourself laughing out loud instead of being repulsed most of the time. It's very effective and entertaining and I actually wish the entire franchise would have been like this instead.

The plots banality has also been cranked to eleven in this and is as over the top as the rest of the movie. It fits really well.

Bottom line is that this movie never takes itself (or anything really) seriously, and that's what makes this a rather excellent closer to an otherwise mediocre franchise.
