Perhaps it's because it doesn't feel like it is really trying anything new. I know they want us to forget about the Bale/McG outing, and that's fine, but this just screams remake while simultaneously employing icons from the original like Arnold Schwarzenegger, as if to say "We have nothing new to add, so here's some of the shit you loved".
I have no problem with a sequel, remake or reboot to The Terminator, but don't try and have your cake and eat it too. Pick what you want to be, and then be that thing. You'd think we'd be more excited about this, with a cast that includes Jason Clarke, Emilia Clarke, J.K. Simmons, Lee Byung-hun, Matt Smith and Jai Courtney...ahh, maybe that's the problem.
Honestly, just thinking about this is gonna make my head explode, just like the old T-800 down below. See, I got there eventually. Terminator Genisys arrives 1 July.
