"Trust me."

Is that line in every movie these days? It's driving me crazy. Don't screenwriters have any ideas anymore for how to make characters talk to each other? The other line I'm seeing constantly is: "What are you talking about?"

Movies today... it's like there are 2 kinds of characters, the ones that say "Trust me" and the ones that say "What are you talking about?" See there's some plan or idea that the first character has and instead of any interesting interchange, they just say "What are you talking about?" and "Trust me" to each other.

Discuss. Without saying "What are you talking about?"!
