I know its received mixed reaction from early viewers.
The 80's action stars in this (plus Statham) are pretty much all of my fave action actors, so it will have to be total and utter garbage for me not to like it.
I will be disappointed if the screen time of the main Guys such as Sly and Statham is limited, but I can live with the likes of Lundgren, Ford, Snipes etc having more limited time.
Looking forward to seeing Gibson - again assume his air time is limited as the movie bills him as "with" rather than "starring" which in itself suggests he has a more minor role - as Ford and Arnie.
I know Stallone was intentionally aiming for this to be the last Expendables movie before he hands over the torch to the younger stars - for the franchise to continue - so that may explain the screen time of the younger stars. That said, he has now confirmed that there will be an Expendables #4 and it will follow the format as the previous movies including the 80's guys - with possibly even Dwayne THE ROCK Johnson as the main bad guy, which sounds cool.
