I loved AI, though I will never watch it again. (it made me cry and though I love crying at movies there are some I won't see again) And yes Gigalo Joe was amazing. I adore Jude Law, so.. Yeah, *grin*

Because you're not a big sci-fi fan, I suggest renting the movie first. Then, if you like that, check out the book. They're very different, the book is more indepth and the movies leaves a lot of things out. But they are both amazing. :)
