Is it me, or is this movie a mess?

I get that a lot of people think that's stupid funny, and a lot of stupid funny movies are great. But this movie is mostly just stupid, and it feels like not that much thought was put into the writing.

It's a bunch of unfocuses shannigans, one not being that much related to the other. But the thing that makes it not work for me, is the abrupt shifts in tone. For example, Tim hates Mickey and wants to be beat him up cause Mickey is Jewish. Tim's friends do not agree with Tim's Jew hating issues. Yet when Tim fights Mickey, his friends are constantly cheering him on in the fight, even though they don't agree with what he is doing.

And what is this Jew issue subplot doing in this sex comedy that has nothing to do with such a theme?

And there are these scenes of cops busting the kids balls, for drinking and things like that. Not just Porky's brother, but other random cops as well. But we don't want to see cops busting their balls. We want to see the kids get into trouble and get away with it. But in a more focused more sharper movie.

It's not just not as sharp as American Pie, or even Animal House for that matter. What do you think?
