I get it: realistic dialogue is unrealistic. The way people really talk is usually pretty boring. People fall back on common sayings, erode vocabulary with profanity, spew trite cliches, etc.
But that doesn't mean it's BETTER to make your fictional characters do it.
This is like....screenwriting 101 here. There's a way to make a fictional person seem realistic, which is often different from what real people WANT to watch/read.
It really is screenwriting 101. New writers have been reaching this "aha" moment since before movies existed.
