The old one, right so that's like saying you can't have a super hero in every episode because a budget wouldn't allow it, (heroes anyone)
Not to mention predator is just a man in a suit... yeah its going to break the budget that isn't it??...lol
Look its been proven time and time again, that t.v series can be way more suspenseful than movies can be. You have a lot of time in a t.v show to work with, to flesh characters out more than you do in a movie. Which would work in Predators favour not against it. Because every death on screen would be felt, because you have had time to get to know them. Also i disagree with you about predator doesn't have a world to explore, if anything predator is crying out to be explored further. We now pretty much know everything there is to know about the xenomorphs. The same cannot be said about Predator. I'v always said this, the problem with Predator is there isn't enough cohesiveness to its story, its this that has ultimately hurt the franchise through the years because nothing really connected together. There is no deeper story line going on where the viewer can look forward to next one. For me a t.v series could correct that.
A t.v show would also allow directors and producers to try ideas out that might not of been passed with a big budget movie. You can take more risks with television and be more creative.
The more i think about a Predator t.v series, the more i see its potential.
