Hex's plot is almost plagiarized from the Will Smith 'Wild Wild West'. Civil War veteran is enlisted by the president to help stop an ex-Confederate crazy from using steam-punk weapons to take over the country. While WWW was fun and campy, Hex's tone is more gritty, with lots of gratuitous violence and rock music. There are some attempts to 'graphic novel' the film stylistically with cartoon overlays and weird special effects, but those seem oddly intermittent, and the film teeters between something like '300' or 'Legend of the Sword' and a standard western.
Hex is not awful, and Josh Brolin is always fun to watch, but the film feels overly dark and joyless.
Erased or Expatriot or whatever (more than one name is usually a bad sign) is an exciting, if flawed, thriller. Yes, the plot is warmed over from many many other flicks. Yes, as the plot is revealed, the writing gets a bit weaker, and there are some odd character choices. Eckhart, despite a lot of his work, just doesn't strike me as a leading man type, but maybe that choice was on purpose so he can play an 'anyman' type of character (with a certain set of skills). But still, the film grabs you with his life getting erased, and then keeps the tension for most of the film.
'17 Again' is a rehash of a LOT of 'if I could do high school over again' flicks, and as such, does not cover much new ground. I also felt the geeky friend was miscast - they could have used someone more colorful like Jack Black or Kevin Hart.
That all said, there were some funny moments, and it was pretty heartfelt. I thought Efron does a good job channeling a middle aged guy. Oddly, while I thought he looks NOTHING like Matthew Perry, he sort of does now.
Shia labouef is a douche because he had an unsatisfactory home life. Repeat 50 times and film it. Bingo, movie. I am sure it is realistic and portrays the human soul or whatever, but absolutely awful to watch. Could have used more cursing and child abuse.
