Appearance of the creatures: Important, but oth look great, no complaints here
Movement of creatures: somewhat pretty important, they need to have consistency with past performances(well, the good ones anyway)
Wolf's vison: I considered it important, but it looks fine, as long as it sounds good, wouldn't ruin the movie for me, but its one of those nice details that show me the Bros care
Predalien: Its the new villian, so its important, but it seems great, I just hope it performs well on screen, and feels as great
Earth setting: I don't like it, but I can live with it, as long as everything else thats important to me in this film is handled pretty damn good to make up for it
Continuity: important, but I've got no worries, as the Bros have confirmed effort has been put into the film to maintain continuity
Human characters: pretty important, I want them to be likeable, relatable to, and most of all, have believable acting
Level of gore: Important, these creatures are brutal, and the films need to portray that, not cut away
Alien gestation period: quite important, I don't want these to be the 'instant chestburster' type aliens
Canon in general: I'd like it to be maintained, little discrepencies get under my skin
Story: pretty important, but its acceptable, as long as it flows well, and doesn't have holes
Music: completely important to me, music has the power to make or break a film, but it seems like this score will do the former for this one
Running time: very important, it needs to be at least 100 minutes WITHOUT credits
Fight scenes: I want them to be viscious and to the death, but I don't want them to feel repetative, each fight scene needs to have its own aspect that sets it apart from the others, like Wolf trying to fight two aliens, or Wolf possibly getting caught without any weapons, etc.
I think I've said my peace, no wait, one more
ENDING: important, I do not want a 'dammit, guess I'll be back here in two years' ending that tells you there will be another, that acts as a cliffhanger, subtle set ups are fine, but having the last 10 seconds of the film reveal something
you didn't expect, that tells you where the next film is likely headed is not something I want to see...
