You know, it's the game's responsibility to capture the player's interest; no customer is under any sort of obligation to grit their teeth and trudge on despite the constant headache the game induces. If the first part is lackluster and off-putting, can you blame people for not having the motivation to continue playing?
Nope, I don't blame people losing motivation, this happened to me in a lot of games, too. But, as I didn't play the Div demo and bought the game at once, I would've missed a lot if I had judged it merely via the Aleroth dungeons (in the demo). Same in the case for BD => Act 1 is a dungeon crawler as some call it. The other acts are different. So, I take Barta's post as a suggestion, what's wrong in that? I don't consider it a blame.
If I dislike a game, I simply uninstall it. Example: I liked the Sacred demo and therefore bought the game => didn't motivate me for long. Is it a bad game now? Nope, just not suitable for this gamer here, c'est tout. Same for other games, such as Arcanum, Morrowind, Gothic 1/2, Dungeon Siege/Aranna, Diablo. Are they bad games? Nope... <read above>. Is my opinion relevant for a different gamer style? Nope.
Winterfox:
And what about the fanpoodles who say that the demo doesn't do the game justice at all, and that you shouldn't judge the game by its demo?
These "fanpoodles" will be put into perspective by other "enlightened" mythological "creatures" claiming the opposite. Opinions will always differ, it's called plurality of taste. No need to discredit either side IMO.

Suggestion: If a demo does not give the correct impression, what about borrowing a game from a videotheque for a few days or from a library to get a better idea if the game is suitable for the gamer or not? Might save frustration and helps to make up one's own mind.
