Yeah, you heard that right. The game is quite excellent. Don't believe me, well then read what I have to say about the PS3 version:
Dead Space Review
I also typed up a review for Silent Hill Homecoming if anyone is interested. Really I think the Homecoming review reads better even though I spent much longer on the Dead Space review. I've spent MUCH more time playing Homecoming than Dead Space at the moment.
I'm also trying to write up a guide for Dead Space but this one's going to take quite a while. I really should have done this on my first time through like I did with SH: Homecoming, since I was much more involved then. I'm using both the 360 and PS3 version to write different parts. Hopefully, I'll have the motivation to continue.
I'll be receiving Far Cry 2 soon, so I don't know if I'll have the willpower to stay focused on Dead Space for the next few weeks.
UPDATE: Just as an extra, check out this Silent Hill Homecoming video review made by a good friend from a forum that I frequent from time to time.
