I also like Roth. Though I sometimes think he should've tried to make more out of his career. But maybe it was his choice to do mostly smaller and diverse movies.
It's been a while since I've seen "R&G are Dead", I'd also say that they are, as the title says, dead. I think I've also seen "Captives" when it was on TV. Julia Ormond may have also played a role why I watched it. ;)

Looking through his long list of movies, I remember enjoying "Gridlock'd" quite a bit, even though it's also been a while since I saw that one.
