Actually, in director's cut, it is made clear that Loomis is alive, though it is not made clear in the theatrical one. As others have observed, just because you were not satisfied does not mean "everybody" hated it. When you grow up, you may learn that yours is not the only perspective in the universe. People seem to react in a negative way to the fact that, unlike Platinum Dunes, perhaps, Zombie likes to challenge the audience by going in directions that were not anticipated. The greats from earlier decades did just that; now a "by rote" approach is to only way to avoid everybody crying about being let down. By the way, Zombie also states that there will be no flashbacks, though there may be some different & "weird" methods used to bring back certain characters. Sit back & enjoy. We don't really know how to make movies; he does.
