I read the first 3 issues of Saga... found it to weird for my tastes but I can see why people like it. I'm a big fan of the writer but the world/setting/weirdness didn't work for me.

Hawkeye has been pretty good if you can get past the almost retro style of art. I'd say picking up the first trade is a good idea... you'll either love it or just think it's ok.

All New X-Men has been better than I expected... was a bit worried about Bendis but I've enjoyed the crap out of it so far.
