Why is Finn still around?
Jar Jar Abrahms really dropped the ball with the Finn character (Well the whole crappy movie really). I knew the character really had nowhere to go by the end of TFA & his involvement in TLJ would feel awkward and tacked on and boy was I right. Why would the "Resistance" feel the need to keep Finn around for any reason other than menial grunt work at best? It just feels so blatantly like "Well he's "officially" supposed to be a main character so we have to give him something to do. (enter pointless side quest)
Jar Jar wrote himself into a corner with Finn by making the character so simple and limited so much so that his ineptness had to be "slightly" retconned(we see him piloting a vehicle).
