When I first watched I gave 4/10, now...
Okay this was the first Wes movie I saw and I absolutely hated it, didn't understand why people found it funny and couldn't keep up with the story to care about the characters. Then a couple years later I watched Fantastic Mr Fox with my younger brother, and loved it. After finding out it had been the same creator I was shocked, and needed more. I would say there is a specific order you should watch his movies in order to appreciate them and understand the style.
1st-Moonrise Kingdom or Fantastic Mr Fox
2nd-Rushmore
3rd- you'll probably be in love by now so watch what you want.
I can't find fault with any of his films now, they are really quite superb and unlike anything you will see. Remember it's DEADPAN humour, I think I was so used to in your face "this is a joke' humour that I wasn't ready at first. Don't give up!
