Hate is probably too strong a word - the game isn't interesting enough for me to hate it. But its extremely disappointing in just about every way. Not sure if it takes Jade Empire's crown as the Bioware game I care about the least, but its damn close.
Ultimately, the game just feels completely flat and lifeless. I have no real interest in my character, my party, the main plot is a joke and the side quests are a nightmare of blandly soporific collecting. The script and dialogue throughout is uninspired in the extreme, providing no depth to any of the subjects covered. Pretty much every single aspect of the lore is handled better and with considerably more depth in the previous games. If you don't know what the various factions, places, peoples are going into this game, it makes no attempt to educate you, and doesn't develop any of it.
Just a horribly shallow experience that is destined IMO to fade away from memory very quickly.
The fact that many critics are going through the motions of fawning over the game means nothing - most of them scored DA2 almost identically and now they apparently hated that game. The critics say what they think their readers want to hear. They put great effort into gauging these things, and usually get it 'right' (as depressing as that is). Sometimes they completely misread the mood about a game (Bioshock Infinite) and are forced to do an about turn and hope nobody notices. Other times they are exposed as not having really played all much of the end and/or not being nearly as fond of the game as they pretend to be (the Mass Effect 3 endings debacle caught the critics completely off guard, because most only pretended they finished the game and the ones that did, didn't care enough about Mass Effect to realize what was going to annoy the fans).
Praise from the critics now will fade very quickly, because IMO its just them trying to keep on Bioware and EA's good side for when Mass Effect 4 comes out and because they knew that many fans would have gone ballistic if they'd criticized the game, even if those people hadn't even played the game at that time. Its all conjecture of course - I can't prove what these people actually think (beyond pointing to the endless amount of times the industry has just flat out lied on topics of all kinds). But I can say that if this game was released with a different, less closely followed and favoured developer name on it, this game wouldn't have been given nearly the kind of free pass this game got. The bugs and crashes alone would have seen it eviscerated.
But quite apart from what the industry 'press' say, I reiterate that for myself, I thought this was a terribly boring game. .
