Since the Blades as a faction lead to essentially nothing, I dislike them.
Since keeping Parthy alive leads essentially to nothing, I think that's lame too.
There should have been some sort of concrete crossroads:
You spare Parthy and in turn gain access to several meaningful quests with him and/or the deadbeards.
You slay him, opening up the Blades as a decent faction with tons of interesting quests and content.
Having neither was pretty neglectful, and I'd imagine that by the time Beth actually releases patches that fix stuff and DLC's that really rock, I'll be enjoying myself in Mass Effect 3 and Resident Evil 6.
