I am a lifelong fan of Sylvester Stallone. FIRST BLOOD is one of my all-time favourites and I love so many of his old-school action classics.
Back in 2010, no one was as excited about that first Expendables film as I was. But unfortunately, this series has never quite managed to live up to it's promise - each installment just seems to get worse - poor scripts, terrible looking CGI blood and green screen compositing, choppy editing and lazy performances. These films barely work as guilty pleasures for me. It's a shame we don't live in an alternate reality wherein a studio like Cannon or Carolco had already made BIG action move team up films, perhaps back in the late 80s, starring Sly, Arnold, Chuck, Dolph et al when they were all at the peak of their super-powers and popularity; perhaps a trilogy of films with competent action directors at the helm (McTiernan, Donner, Hill...) with a memorable soundtrack (Goldsmith, Horner, Silvestri).
Sadly, what we DO have just doesn't work. I watched the fourth film last night and... oh, man... how sad.
If you want to see Sly in a film featuring an ensemble cast, with GOOD acting and a tight script, may I suggest the vastly underrated COPLAND.
