Breaking it down as simply as possible:
Resident Evil 1, 2, 3, CV = Alien = horror
Resident Evil 4, 5 = Aliens = action
I'm a big fan of both movies, but I think Alien is superior. I'm always a horror guy, and Ridley Scott made an excellent horror movie with Alien. That film was a prime example of survival horror in movie terms.
On the other hand, Jim Cameron took Ridley's film and the ideas he put forth and took it to a new level. There are still horror elements in Aliens, but now, instead of being weaponless against one tough baddy, the heroes are armed to the teeth but the enemy has upped the ante.
Even in structure, the two are similar. In the original REs, you're exploring a confined area, similar to the Nostromo. In RE 4 or 5 you're movie from area to area within a region, similar to the marines moving around the colony on LV-426.
