Whilst CIA agent Frank Moses (Bruce Willis) enjoys the quiet retired life with Sarah (Mary-Louise Parker), she longs for some adventure which is why when Marvin (John Malkovich) shows up whilst they are shopping she can't wait for some adventure. It seems that some one has published a file which states that Frank and Marvin know where a portable nuclear weapon is which was smuggled out of Russia. It leads to the two of them accompanied by Sarah trying to track it down whilst various top agents from around the globe are hired to try and get to the nuclear weapon before they do.
To put it simply "RED 2" is trying to outdo "The Expendables" with the various actors it digs up to embellish and already entertaining cast. As such on top of the returning Willis, Parker, Mirren and Malkovich there is Zeta-Jones, Hopkins, McDonough as well as Lee. It is such a fabulous cast and each play their parts well from Zeta-Jones giving us femme fatale to Hopkins giving us eccentric scientist. But there is more and "RED 2" not only features some snappily ridden dialogue but there are also many an entertaining action sequence which has a touch of the comical MacGyver about them. I wouldn't go as far as saying it is full of spectacular action but certainly crowd pleasing acting.
The trouble for me with "RED 2" for me is that it is in such a hurry to move along, to bring in the next cameo or deliver the next moment of action it starts to become less a movie with a storyline but a showcase movie of ideas and cameos. For those who enjoy set piece movies this will be fine and dandy but for me well I wanted more and that more got lost beneath everything else.
What this all boils down to is that "RED 2" is still an entertaining popcorn movie but one which will appeal more to those with a low attention span who will enjoy the way it sprints along delivering one set piece after another.
