I think the tagline to the recent action film Taken should be:
"You will believe that Liam Neeson is still a complete bad ass."
If all action movies were this well made, I probably would go to more of them. It wasn't overflowing with intelligence or anything, but there was a modicum of smart believability, just enough to carry it off.
There were some small issues, such as the overabundance of the Daddy Knows Best syndrome, the fact that in reality, those who operate in human trafficking (the bad guys in the film) rarely pick rich Westerners as their target.
However, it was a very satisfying, fun, dark, and brutally gruesome movie. Liam Neeson carried it off well. Its hard NOT to want to watch human traffickers get the living shit kicked out of them.
