Don't bother. Mass Effect 2 is just as horrible in my opinion. I'm completely serious, the voice acting is just about the only good thing about these games: the visual style is ugly (the style, not the graphics), the characters are flat and uninteresting, the setting is as generic as they come, the story is pointless (and has the exact same structure the rest of modern Bioware games have), the gameplay is that of a clunky third person shooter with some horrible controls and a superfluos excuse for a role-playing system. I was so excited for the first game when it came out and it turned out to be so utterly shitty. Yet I somehow managed to finish it, then finally tried playing ME2 years after its release and just couldn't make any significant progress.
EDIT: Oh, and a really crucial thing. There is not enough space in that game, which is important to me as a sci-fi fan, but somewhat hard to explain. It doesn't feel like you're traversing the galaxy, there is no sense of exploration and adventure, probably due to every space trip being a really short cutscene in which your ship teleports to another planet and how casual every character is about space travel. All the planets you can "explore" only detract from the experience, with the copypasted excuses for sidequests in the first game and the pointless yet compulsory for the good ending minigame in the second. The games might as well have been set on a single planet, it wouldn't really change anything plotwise.
