It was definitely one of the most frustrating games I've ever played. Hell, I could have talked about this in the Frustrating Games thread from way back. Still, I really enjoyed the Time Trials. It was fun trying to beat your "shadow". I thought that idea was brilliant, as it tempted you to keep trying.
I'm thinking more of the terrible controls on the xbox version, the laughably bad storyline and the shallow characters. Seriously, how long had I known the last boss? A total of 2 minutes, come on! Also, anyone that didn't see the "twist" with the woman in white coming from a mile away with the headlights on is either an idiot or has never seen a movie or game in their life.
I hate Mirror's Edge with a fiery passion. But I'll stop and get back on topic.
Husks in ME2 creep me the hell out, not sure why...
