Jessica Alba is totally hot, there's no denying that. I don't think I've ever seen a bad picture of her. The odd thing about her, though, is that she really seems like nothing more than a good-looking girl. She has no presence, and her acting ability is marginal, at best.
I'm kind of worried about how good Fantastic Four will be, seeing as how she has a fairly substantial role, and probably won't bring much more to it than filling out her costume really well. On the other hand, Sue Storm is supposed to be distant and closed off, so maybe it's the right casting after all.
Regardless, Jessica Alba is still totally hot, and in her next movie, she will aparently be wearing a bikini for much of it. Now that's effective casting. Here's the trailer.
And here are some great pictures of Jessica Alba from the new issue of Arena.
