I liked. I thought it should have been longer. The parts that worked, worked well. The parts that didn't moved along before I started squirming.

I disagree. You can see the cynicism ALL over the place in that movie. The vogons show his distaste for government, very clearly. The church of the white hankey, for organized religion. Its very clear.
