It’s proven in most stories have a major boost when great characters are a part of them. Learning how to right dialogue lends a big helping hand in exposing a characters needs and interest’s which drives the story further.
Good dialogue- A good writer would use subtext, in which the character’s convey’s a hint of what a there feeling with certain word choices that aren’t surface level. For example, Kenny is really angry with Matt because he left him to hitch hike home after a party, and this how he approaches him. “You know, I lived five miles away from where we were at, and I think you may recall this but, it just so happened to be…raining! We know from here how approachful and angry he is from the way he builds on his frustration, while also playing with the obvious circumstances Matt put him through, also making Matt Feel quilty. Another example is from the film Rocky, when he flirts with Adrian and he say’s this line “I’m gonna go home and come up with another joke for you tomarrow”. This shows that Rocky won’t give up when it comes to getting with Adrian, using his charming side to make it feel well delivered, while also hinting on his powerful persistence that will progress later in the film.
Bad dialogue- Too on the nose. Revealing too much therefore not leaving any stakes to intensify the moment. In other words lets take the same situation with Kenny and Matt, and change it up a bit, having Kenny come up and say this instead.”I’m so angry with you”. It’s not natural. Imagine if in Rocky where he’s flirting with Adrian about how he’s gonna come up with a joke at home, he instead say’s “I’m Persistent”.
