Just saw Gamer yesterday with my step-daughter and was largely let down. Butler was okay (my hat is off to any leading man who does not rely on "pretty boy" looks.) All I will say is that the majority of the movie is filmed in what I lovingly refer to as ADHDvision. More information than you could possibly take in, with scenes comprised of roughly 2 to 3 cuts/jumps per second. It just doesn't appeal to me. Spastic film making does not automatically translate to "action" for me. One nice continuous shot once in a while wouldn't kill the movie. Notice that I said "kill the movie" as opposed to "kill the plot". The plot was an underdeveloped snippet of a mildly interesting idea. It went nowhere with minimal details and the resolution was predictable and weak. Sorry if this seems overly negative. My step-daughter liked it (although she admits that a good portion of the reason for that was Butler with his shirt off) and you might, too.
Lastly I will place the following in spoiler tags due more to mature content than it containing actual spoiler material, although there is a slight element of that:
