Yeah that's something I'll give to the Slyster, Housester. He's got an Academy Award Winning film under his belt that he wrote, when those awards actually meant something. The last Rocky film was decent enough, but Rambo 4 was fucking great and he was well into his 50s in that.
Arnold is just doing direct to video shit now while Stallone is mostly doing shit that he himself is writing, directing and producing.
When you look at both of their careers, Arnold has done way less since he jumped into politics as you said when he was falling off. I really only care about the first two Funsternators, Predator, Commando and The Last Action Hero. The rest of his stuff could be tossed into a dumpster. I never got the appeal of the Conan the Funstarian films.
Stallone has six Rocky films, and even the ones you would consider bad are still very watchable. All the Rambos are solid, even the last one with his ridiculous level of violence made up for it. Cobra, Over the Top, Cliffhanger, Judge Dredd, Demolition Man, The Specialist, and Cop Land are all watchable films.
What does Arnold really have beyond the ones I mentioned? Eraser? The 6th Day? Junior? Kindergarten Cop? Red Heat? Twins? I never got the appeal of Total Recall. Gave it one watch and was meh through the whole thing. Running Man stinks.
Outside of T2 and The Last Action Hero, the only other 90s film any good is True Lies. Stallone has several in the 90s that were decent enough.
