Nothing, be proud of your opinion....enjoying things is a good thing....it's always better to have enjoyed a movie than to have been disappointed by it...you win in the end as you gained fun from it. But just don't attack shinobi san for his opinion lol.
Not seen either John Carter or Battleship...actually maybe I saw half of John Carter.
I think sometimes seeing a movie years later can change your opinion. It happened with me for Batman Begins...but that's because I just didn't understand the movie when I was 13 years old...and my mind was completely blinded by Star Wars Episode 3 Revenge Of The Sith's awesomness at the time.
Then thanks to TDK I never bothered seeing Begins again till a month ago...I was blown away then. Best origin story ever.
