Off the top of my head
Death Proof- I thought it was going to be a boring movie with car races but it was freaking awesome
Skyline- I believed it was going to be a District 9 knock off but I actually felt for the people dying. It was much better than Cloverfield ugh
RAMBO - Old Man Stallone, and all the other Rambo's after First Blood kind of sucked hard. But then the trailer came out and Old Man Stallone is awesome. Then saw the movie and it became one of my favorite action movies. Now any new Stallone action movie gets me excited.
Punisher: Warzone - After the Jane one turned out mediocre with very little graphic violence I didn't expect much here. And then Titus Pullo starts pulling some Friday the 13th shit and I loved it.
Blade Trinity - No Donnie Yen and Guillermo, a lower budget, and Wesley Snipes having more input... No thank you. Then saw it, Ryan Reynolds basically being Deadpool, and Biel Looking super-duper-outrageously hot shooing a bow... Awesome-sauce.
Despite having my doubts or having no opinion initially I thoroughly enjoyed Dodgeball: A True Underdog Story, Zoolander, Freddy vs. Jason, Alien vs. Predator, Equilibrium (watched it only because it had two of my faves, Christian Bale and Sean Bean, but ended up really liking it.)
I thought Ratatouille would be a typical boring family movie, but it turned out to be one of the most interesting family movies out there. Same thing with Toy Story 3.
Once upon a time, I was offered to go along with a friend's family to the movie theater. I only went because they had CAR PHONE and I was blown away by that.
They were going to see Billy Madison, which I had exactly zero desire to go see, but I was in it for the car phone, lol.
Freaking loved it, like changed my 11 year old world forever.
It's nudie magazine day!!
and foolish though it may seem, to me that's everything.
