You're seriously going to call an entire game terrible because you didn't like the first 45 minutes? And then you list a bunch of reasons (which I all debunked), that are based on those 45 minutes of playtime, while most of the objectionable content are simply not present in the rest of the game?
Seriously, you call the characters boring while all the fun characters appear a little later in the game. You call the game less sandboxy even though you only played *45 minutes*?
And again: not liking the game is not a good reason for calling it terrible. If a game reviewer writes a review about NWN2, lambasting it because he hates RPGs, then everyone bals at it. For good reason.
As a comparison, Fallout 3 is a poor game because it is buggy, its writing is terrible, its characters are bland and one-dimensional, the choices you make have very little consequences, and there is almost no practical difference between your character development choices.
Those are all verifiable reasons based on a full playthrough. Not a list of minor gripes that aren't even based on giving the game a decent amount of time.
