Hulk was wondering. Is it OK to have liked Battleship? Hulk know it not a GOOD, high-quality film, sure, but Hulk enjoyed it. Hulk liked the action. Hulk was big fan of board game back in the day, so Hulk can understand why they take approach they did and add aliens.
Think about it. No one would pay to watch 2 hours of 2 kids bellowing out random letters and numbers. So, they do this instead. Hulk liked the movie, but Hulk didn't think it was "good".
Maybe had they not put it in same weekend as Hulk's Avengers movie and put in July, it would've earned more. The only thing Hulk wished was in the movie was a nod to the board game in the form of one of the characters saying, "You sunk my Battleship".
Plus, Hulk thought living metal wrecking balls with spikes were pretty cool. They smash good.
