My (then) 3 year-old nephew was obsessed with this movie and I had to watch it a billion times and I hate it. But yeah, there's nothing too out-of-the-ordinary with thinking a CGI girl is cute (seems like most M-rated video games have sex scenes these days). I mean, when I was a kid, I was crushing on the lady fox from the cartoon version of Robin Hood. Now excuse me while I go to the store for toilet tissue and VHS cleaner.
I've never actually seen this movie, and the woman and bee dating? Aside from the most retarded use of magic I can possibly imagine, I don't see how this is supposed to have a happy ending.
He finds out that humans consume honey so he sues humanity. There could have been a way to make this concept funny, but Jerry Seinfeld decided against it.
The plot of the movie centered on a bee falling in love with a human to the point where she leaves her human boyfriend to be with the bee. At no point is this ever questioned or considered strange.
