I enjoyed ME and ME2. Having said that, people are overhyping it. You must also recognize that Mass Effect 2 is the middle child, and as such feels unfinished, because it /is/. It's still great, but the story won't be as involved as the first one simply because it's leading up to things that won't be important until ME3 for the most part. Having said that, I still loved it, the characters are so fun.
Also, I think despite what everyone has said, you must think very carefully about it. If you love DA:O, you may not like ME or ME2. It draws a person of different interests.
I would also strongly recommend that you play ME because the situations in ME2 will carry far more weight and feel a lot more meaningful to you. But understand that you'll be then faced with a problematic fighting system and horribly boring sidequests on the Mako. The story however, is solid.
