Just watched this film...a few points and questions [SPOILERS]

About the last scene with the suit.
I´ve got the feeling that they just wrote this in for a potential sequel with human predator.
In the movie it seemed to me that the Predator was just randomly dropping onto earth with his broken ship after being hunted by the bigger Predator. I didn´t think it earth was his real destination, he was just trying to get away quick before being hunted down.

The plot was all over the place anyway, they should´ve kept it waaaay simpler in my opinion, with less characters.

Yea what was the deal with the plasma cannon. In previous movies the predator has full control of it and acively aims a triangle onto the target. 3 laser dots externally represented by an actual triangle in the predators helmet vision. Point and fact we actually see the predator fire at falling rocks in the first predator movie, something we woulden't expect an automated system to do. In the earlier films it doesn't look automated at all. I'm thinking this autofire angle is due to a misinterpretation of a scene in predator 2 where it appears to target keys(note the keys in this film is the real life son of busey keys who plays keys in predator 2) then fire as the predator seems to look away from keys. Predator is focusing on danny glover while the canon finishes fireing on keys. Other then that the plasma canon should not have a mind of its own.

I agree the kid being autistic and treating autism as if its a step forward in evolution is pretty dumb thinking as well. Even high end autistic people have a hard time coping with the world. I can't imagine some 12 foot tall predator would consider human autism to be a trait of a warrior.

Also how does shooting an Alien dog in the head make it tame?

I'll have to read up on the sex offender scene.

That just looks like the predator in general. I pretty sure buffy borrowed that from the predator films.

The robot suit was embaressing

I doubt they'll have the sex offender scene in the deleted scenes. That just defeats the purpose of cutting it in the first place. Most scenes are cut due to the pressure of the studio to make the movie shorter to squeeze in one more ticket sale. but in this case it was removed for what seems to be political reasons.
