Last Man Standing - Remake of Fistful of Dollars (which was itself a remake of a samurai film as mentioned above) was a very good retelling of the story. Bruce Willis and his never ending ammo in his 1911s was a bit much, but I really enjoyed it.
MacGyver, Hawaii 5-0, Magnum P. I. we're all terrible remakes of classic TV. Just unwatchable.
Robocop reboot wasn't bad, but it want good. There was one line I remember from the trailer that killed it for me before it hit theaters. Robocop got his new, black armor, and his partner says, "now you're the right color, I know I can trust you." or something like that. I don't even know it it made it to the final cut of the movie or not.
True Grit has been discussed ad nauseum. It worked for me, even though I do love the original. Both are good. I took my mom, who loved the original, to see the remake in the theater. When the credits rolled, she saw Jeff Bridges name, looked at me and asked, who did Jeff Bridges play? He played the role so well, he became Rooster, she never even saw the actor, just the character. That's how I know they did the role well. It's rare that I never once see the actor, only the character they portray.
Magnificent Seven, the latest of the latest remake, couldn't maintain my interest. I saw it, but I don't really remember much about it. So there's that.
GB16 just wasn't as funny as they thought it would be. I hated Bill Murray in that movie. There, I said it. I'm a big Bill Murray fan, but he should have passed on GB16. Or had a small cameo role like Dan Aykroyd.
I hear they are doing a Six Million (or in this case, Billion) dollar man reboot movie with... Mark Wahlberg.

I can only imagine how bad that will be.
