Really liked the first 2 of the Dark Knight trilogy but I thought The Dark Knight Rises was dreadful, couldn't even finish it. I know I'm in the minority. Haven't seen the Expendables or Grudge Match, they looked over the top silly but I'm a sucker for Rocky and Rambo. Have enjoyed pretty much every Rocky as for Rambo, First Blood and the last Rambo were great.
Rambo Whatever, the last one, is probably the only thing close to the Death Wish type of movies made in the last decade. I laugh every time the pacifist do-gooder turns killer at the end (after having been such a to Rambo throughout) and then gives Rambo the little wave goodbye. You got to just watch these new Old Sly movies for what they are---fun.
Grudge Match is definitely worth a watch. It is a
little more serious than The Expendables, which practically mock the old 80s action movies with all of the gray-haired stars making cameos at least once or twice, and it has Deniro in it. If you ever wondered whether Rocky could take the Raging Bull, it's your chance to find out . . . .
P.s. I understand your feeling about DK III. I think it just needed editing. Whenever I watch it, it, I start at the scene when Bain breaks Batman, and go from there. The first hour or so, outside of the the opening sequence when Bain abducted the physicist, is boring and drags on way too long.
