The problem with that guy is that he expected the game to be bad, so he was simply not willing to spend the bit of effort required to learn how the game is played. If he was, he would have found out that you can see doors (and other objects) with the ALT key, and that you can autotarget with the CTRL key.
Luckily, few people will ever find his review and read it. Most people wanting to try a new RPG, go through major gaming sites and read reviews from there and download demos and stuff. That's how I came across DD anyway, so I wouldn't pay too much attention to that guy.
