Personally I though ME1 was massively overrated. The combat especially was easy and repetitive. I made it quite close to the end and then just sort of moved on without ever returning.
That said ME2 is brilliant. It really takes a lot of the good stuff from the first one and nails the stuff that didn't work. Combat is fun and varied, and the storyline is much deeper and fun. I was hesitant to pick it up for my PC, but thankfully it also doesn't share some of the massive technical shortcomings of the first one on 360 (which is the version I played). The screen tearing on the original was a game ruiner for me in many ways. I hear ME2 is quite improved on 360 as well, but I haven't played it there.
