Ico for ps2. Any good?

I've heard good things and generally reviews are good for this game, but it seems pretty odd. I usually don't mind the run about the place looking for stuff, type games. What are your impressions of it? Worth a purchase?

very underrated.

if you don't want to buy it, atleast rent it, you won't be disappointed.

definately a great game. worth a buy imo, cause u can find it real cheap nowadays.

thanks for the responses.

Yes, it's awesome. Play it ASAP.
