I whish there was more conflict between the two, they tried a little with the “your no Leia” scene but we needed more, TLJ should have had the two them go out on an adventure while being in conflict , perhaps Poe hates the stormtroopers and is eager to kill them, perhaps he seeks revenge for something they did to him or his parents, Finn on the other hand would try to help them, seeing the light in his former comrades, Poe opposes and so you have a back and forth tension throughout the film leading to a resolution that progresses their characters.
