Well, I think that unkillable enemies is really frightening and stressful. In fact, SH4 had some unkillable enemies and they scared the hell out of me (In SH2 pyramid head also had an unkillable scene if I recall correctly). Maybe all unkillable enemies it's too harsh, but I think it's a brave movement.
And no, for me SH is not about weapons. In fact the more combat oriented SH3 dissapointed me focussing more on enemies. I would have like some HtH combat though, because it's very stressful.
The thing that makes silent hill to be in a league of it's own is the atmosphere. SH2 had a stunning atmosphere, I remember I felt like I'll start crying in the burning scene near the end of SH2 with Angela Orosco. It didn't happen to me before. Besides, the re-playability of SH games is great usually (for it's genre), as they have many interesting endings (and some funny ones). The re-playability of this game should be even better, because the game changes with your profile... that's awesome.
I will buy it within a month, definitely (at this moment I don't have my wii). But well, truth is my intention was to buy it no matter the critics (unless they were really really bad).
