Taken is a good action movie. Quantum of Solace is a bad action movie. Very bad. The problem I have with the direct sequel to the very good Casino Royale is that there is too much action. A car, boat, plane, and foot chases all in the same movie? That might be ok if they didn't sacrifice story in order to do it. The action was even that entertaining either to make up for it. Nothing original, everything had been done before. The cutting was way too fast too and made it hard to watch because every cut seemed like it was under a second. The bad guys were forgettable.
Taken on the other hand had had everything you would expect and more. A simple straight forward plot with a fast moving story. Highly entertaining and much more believable than Bond.
