How completely great (no spoilers!)
I loved it. I saw it years ago as a teenager, but I really enjoyed it. I thought his character was great, kind of nerdy and awkward and cluelessly slimy. And yet he is sweet and likeable too. I thought Goldie Hawn was great too, very shaggable back then and worked perfectly as the carefree young American girl.
I like the zaniness of the movie too, live isn't always straightforward with clear cut ups and downs. Some times things are complicated and strange, but interesting nonetheless. I think this movie comes from someone who appreciates that.
