So, Predator 2 is a pretty good movie and has no Arnold... but at the same time Predator without Arnold ist shit... make up your mind dude.
Predator doesn't need Arnold, the movies aren't his story and have never been one connected arc anyway, so it really doesn't matter.
I agree that the cameo at the end would have been lame, so in my book, not having Arnold in the movie at all is the better way to go... i love Arnold, but people don't give a shit about his movies anymore, the last two went straight to DVD and that should teel you something... it's 2017.
Either it bombs or it makes money, Arnold wouldn't have changed anything about it.
I think there are two schools of thought when it comes to the Predator in general.
Side A- Predator is
the character, Predator is what the movie should be about, their world, their universe, they get the screen time etc...
Side B- The human characters are the lead(s). The story, the mystery, the slow burn of revealing Predator etc... is what it's about. Arnold and Danny Glover both I think were strong characters, that you rooted for, related too etc...
I've said in this forum before. Now it's about rooting for the Predators, them being the main (lead) character etc...
I think Alien franchise did a good job of making it Ripley's story, vs. the Alien story. I always think that's a better formula. When you are making a monster/creature franchise, I'm in the group that prefers humans being the central character vs. the creature.
Now the whole Dutch thing, 30 years later, we've obviously lost out on some good years worth of story...but, nevertheless it would help fill a void in the franchise. my opinion.
