Only problem with the thermal clips was that they made fuck all sense fluffwise. Just like removing them again would. "Oh hey every gun ever was "upgraded" to this new "no longer infinite" ammo system because... um... downgrade! Oh wait never mind they were all changed back after a trial run of less than a year!"
Speaking of things that made fuck all sense from any perspective: Quarians! "We have no immune systems because spaceships! Oh wait just kidding we have such hyperactive immune systems we're allergic to each other, and air! Because spaceships!"
Speaking of Quarians, anyone else get reminded of anteaters by their masks, especially the males'?
After the annoyance that was ME1 (50% inventory management, 40% running around doing pointless quests, 10% fun and interesting plot-related stuff), I haven't considered ME2 worth getting. Without having played ME2, there's no point getting ME3, of course.
Note that ME2 told the inventory management bullshit (with its retarded interface designed for lolconsoles) to fuck off, and eliminated 99% of the superfluous wandering around looking for where you're going, and is still just as long. Combat was also vastly improved from the "go biotic, kill everything with magic blackholes!" theme of the first (although, admittedly, the endgame, even on insanity, was essentially like that no matter what you played, although engineer required a little more thought than just random biotic spam...).
