This is the movie poster equivalent of the morning radio show hosted by a coed team of unfunny, bland dolts affectedly laughing at the stale, "safe" jokes they bought off prepburger. This poster is shorthand for, "These two are sassy and incorrigible! Exclamation points! Stay tuned for the credits to hear Natasha Bedingfield's "Feel The Rain On Your Skin"! You like that, right?"
And if you do like that, congratulations. You're the reason we can't have nice things.
