I made some purchases and watched some this weekend:

Olympus Has Fallen- Netflix (purchased later)- It's an action movie with an easy plot. I like it. Butler plays a tough guy and the stunts are not too unbelievable. Maybe some of the knives to the brain, but nothing major.

London Has Fallen- Digital (purchased)- Part two. Follows the same formula as the first one, believable stunts, but the plot is different and it's not Olympus has fallen but in a different country.

Angel Has Fallen- Digital (purchased)- Part three. Same thing, but different plot, plus he acknowledges he's getting old and it's tough. No more Aaron Eckhart. Now you have Morgan Freeman as the president.. Nick Nolte joins the crew.. It's good.. It's got a little bit of a twist, but if you're paying attention you won't get lost, hell if you're half watching it, you won't get lost.

One thing about Angel vs Olympus is that unlike Stallone or any of the aging actors in action movies, Angel does show the hero being human and has faults.
