I stumbled across this video recently, and I have to wholeheartedly disagree. Sure, Witch Hunt wasn't the best game of the year, but it did have 1. Reasonably fleshed out characters, 2. a semi-reasonably story related to lore items placed in the original game, and 3. it gave closure to the original storyline IF you were (SPOILERS) a male character and pursued a romantic relationship with Morrigan. I'm not sure if it had to with the fact that I still carried/wore Morrigan's ring, but Morrigan went into a fair bit of detail (relative to how much she usually divulges) about the main character's son, his safety, her feelings towards the main character and whatnot. Anyone who claims that the main character entering the mirror portal with Morrigan is a cliff-hanger ending lacking finality probably thought Frodo needed to napalm Mordor after the line of Kings was restored, or that the end of FFII (US) lacked resolution.
Well, I just played Witch Hunt and I actually liked it. At least it's better than Warden's Keep or Return to Ostagar which was total fail. BioWare probably couldn't afford Claudia Black to star in the entire DLC that's why everyone is so dismissive of it. But yeah, Morrigan could've been less ambiguous about her plans.
How does it not answer any questions? it tells you what happened to morrigan and the god-child. What other answers were you looking for?
