Slant Magazine gives it 3 out of 4 stars and concludes, "As ludicrous as it is to see this troupe of largely past-prime action-movie icons manically reassert their own box-office primacy, there's enough empty calorie fun to be had in humoring their shared fantasy that they're not getting too old for this shit." Rolling Stone gives it 2 out of 4 stars, saying, "This sequel doesn't wear down your resistance; it just wears you out." DVD Talk says it's "bloody fun and greatly improves on the mediocre first film." Entertainment Weekly gives it a B and closes with this:
Assigning artistic values like ''good'' or ''bad'' to The Expendables 2 is a fool's assignment. The movie is excellent crap, fine junk, an exercise in campy movie nostalgia, and a demonstration of American supremacy in the field of nutty cosmetic enhancements for aging movie stars. I had an inexcusably fine time studying movie-star hairlines and admiring their willingness to let us gawk.Rotten Tomatoes has a critics score of 65%.
