Interesting; thanks for your thoughts.
I just expected the training to go a bit deeper (I mean, Fisburne's character barely taught him how to use a gun, and before we know it, he's giving up on the Charlie character and claiming "he can't be turned into something he's not;" I just felt this was rushed). Now, I understand that he couldn't be turned into this James Bond-Jason Bourne mutant combo overnight, and that wasn't the point -- but I just felt like his training could have been explored a bit more, and that he at least showed off SOME of the skills in a fist fight at some point (perhaps not taking on a nine-foot-nine roided-out goon, but you know what I mean).
I was also somewhat disappointed with the ending, as it didn't really resolve anything, outside of
Charlie's own satisfaction in seeing the head terrorist's face when a gun was pointed at him;
I don't know...I feel like he should have gotten some kind of more dramatic revenge after everything he went through. A lot of people don't realize that this was like the third or so film adaptation of a book from around 1981, as well, so I'm sure liberties were being taken.
Definitely not a bad film in any way; just a one-time-only for me (as a 4K rental).
