AVPR is the tale of several aliens and one predator set loose in a small Colorado town in the early twenty-first century.
The most trenchant observation I can make regarding AVPR is that it represents the first film in either classic horror franchise that feels it necessary to spotlight teenagers skinny-dipping in a high school pool after hours.
Once upon a time, neither franchise required stripping high-schoolers to draw enthusiastic audiences.
But the best that AVPR can muster is to steal a page from the 1980s slasher film formula: vice (sex) precedes slice-and-dice or in this case, attack by alien.
AVPR also puts the final nail in the long-erosion of the "un-killable alien" meme first realized by Ridley Scott in 1979. In his original film, the alien couldn't be killed, and couldn't even be stopped. You just had to get away from it...to leave it behind floating in space.
That's just one incredible gap in situational logic, but there are bigger fish to fry here.
In the final analysis, AVPR isn't merely an insult to the intelligence, it's an insult to the great tradition and lineage of Alien and Predator films.
A requiem, by the way, is a hymn for the dead; a musical composition for the expired.
