I voted for AVP-R hands down.
I enjoyed AVP, but my biggest problem with it was the whole very PG-13 feel the film had. It was a sugar coated AVP vision. You can tell the movie tried it's very best to not be too violent or too gritty. There are many cliche scenes in it, but through time I did warm up to it and just saw the film as a guilty pleasure.
I mean, you have to make a choice here, your a hardcore AVP fan, you can either stay mad at it and suffer forever, or just warm up to it because the truth is it's really not that bad of a movie. There is a fair share of people who really liked it, it did very well in the box office and the movie overall is entertaining.
AVP-R
Not a masterpiece of course, but the reason why I voted for it was because it felt more like a AVP film, just by the simple fact it was finally a hardcore rated R movie. For once we finally got a real tough good looking Predator. The Wolf has character, has a mission through out the film, the Wolf played a great role I felt. The characters this time where much easier to relate too and had something the other film didn't give most of the them......lines.
Less cliche in this movie, you can finally sit back and just enjoy it all. The action scenes were short, but short and sweet, and there were a lot of them! Each one hard hitting and violent. The Aliens were great, plenty of Alien death to go around and plenty of Aliens to run muk. Overall it was way more fun! More bloody, more violent, better acting, a phenomenal score and lots of fast paced action scenes to keep you seriously entertained.
-- I could continue all day talking about AVP and AVPR, but overall I enjoyed AVP-R way more than the first one. Even though, I ummm.... I seriously disagree on almost all levels with the negative reviews the fans have about these two films, this is just my opinion on them and in no way am I trying to change anyones mind.
