Whoever rates this a 4 or 5 stars should never be a movie critic.
I'm an 80s action movie fan and I was NOT impressed with the latest installment. Expendables movies have a few draws normally. Big cast of superstar level action actors and big explosions/action sequences. Well the cast is paper thin this time around with new additions of megan fox and 50 cent, neither of which are action actors, ones not even an actor! And the explosion CGI was awful. Everything looked like they hired a high school AV group to do their special effects.
At best, watch it for free when its released on a streaming service. Dont pay to see this in theatres you'll regret it like I did. Also, I paid for D box seats in the theatre for the extra experience and the timing on explosions and the seat rumbling were out of sync too. Not much good I can say about this one.
