Now, on to the added footage. Does it make the film much better? No, not really, but it does off a slight improvement in terms characterization and also restores some snippets of trimmed gore and effects footage. There really isn't anything of great important put back into the movie at all. There are some extensions to various bits and pieces of dialogue and some of the kill scenes go a little bit further and a couple of the battles go on a bit longer but that is about it. Don't go in expecting a different movie, as you're really not going to get one out of this release. Most of the character development that is added, and keep in mind it is minor, happens in the first half hour or so of the film while the added action and violence is in the last half hour. To this extended version's credit, however, there is an added scene that does do a better job of explaining why the Predators are here in the first place and that fills us in on their ways a little bit more.
Fox has done an excellent job on this release – everything earns top marks from the audio to the video to the plentiful and interesting extra features – but the added footage doesn't raise the feature itself above mediocrity. AVP: Aliens Vs. Predator – Un-rated Director's Cut isn't a horrible movie, it just isn't a particularly good one and didn't come anywhere close to the potential that it had. That being said, Fox has put so much into the supplements here that it'll take you hours to go through it all and if you were a fan of the film, you'll be all over this set. Recommended for genre fans, a solid rental for everyone else.
