Rodriguez is amazingly prolific even if his films are uneven
I've seen all of his films outside of the family features (Spy Kids, Shark Boy/Lava Girl), and I gotta say I've found something valuable in almost all of those. The Faculty is by far the most derivative and disappointing mess out of the bunch (Kevin Williamson only made one good film), but I've been able to ignore it and it really helps that Rodriguez has decided to do the same. Actually, I was so turned off by the film at the time of its release that I stopped paying attention to his career until I found out he shot another Mariachi sequel in 2001. I've been pretty adamant about keeping up with his projects since then.
The thing that frustrates me right now is that even though he's one of the Weinstein's biggest guns, there's still films of his they don't want to release. Even though I found Roadracers to be a little bit of a letdown, it really seemed to fit his extended filmography and I've been itching to revisit it for years. Unfortunately, it's just another movie Dimension is going to continue sitting on... the same with his written/produced horror movie, Curandero. Hell, nobody even seems to realize that movie exists! I think they played it at maybe 2 or 3 festivals before it disappeared into limbo with the Weinstein's exit from Miramax.
Anyway, I'm hoping that with the DVD release of two entirely new Rodriguez films, they might be keen on finally putting out the other two. They did plan on releasing Roadracers to coincide with Sin City's DVD, but they pulled it at the last minute.
