I watch 'QaF' on and off - I actually got hooked on the original British series (brilliant!) and I always found the US version a poor second cousin. Except, that 'Brian' is *so* amazing, he's reeled me in :)

I like Brian/Justin, but I find Justin very young. Brian/Michael is not hot for me at all, although I realize that this is probably the most important relationship in Brian's life. I find Michael so dull though - it's hard to stay interested.

I have no recommendations about fics - sorry!
