I never really took the first 2 Resident Evils as horror games per se. I mean, sure, they have horror elements in but I always felt they were more like modern (at the time) adventure games that happened to have very light action in. I mean, Gabriel Knight has horror elements in it and you can die in it but it's still strictly viewed as an adventure game. 3 was more like a horror game because of how the Nemesis gameplay worked - it made it a lot more scary and fluid, rather than just a few enemies boxed in a room.
4 wasn't scary at all - and my god, did it drag on after you got out of the village parts. I really don't like it, but it did have its moments like that part where you have to barricade the house and then defend it from zombies. It always makes me laugh that people that love RE4 but hate RE1-3 will say "Yeah the older ones had a crappy control scheme and RE4 totally fixed that". It has exactly the same tank controls, the same controls in every way, although now you can aim more specifically rather than just switching between legs, head and body - though wherever you aim, it still comes down to those parts plus hands if the enemy is holding a weapon. All they did was move the camera behind the character.
As someone who found Dead Space a nice idea but actually boring as hell in practice - and totally characterless - what are the chances I'll like Dead Space 2? The first game felt more like a game that should have been called Space Handyman that was being played on a TV with the brightness too low. In fact, if you watch the Zero Punctuation review of Dead Space 2, that's basically how I feel about DS1 and how I'm expecting to feel about DS2 - I just want to like it, though, because the idea is quite nice. It was done better in Dead Space Extraction, in my opinion.
