Number one, I want Molly back and to know what she’s being doing. A step backwards in time to see what the hell happened at home with CJ, PTSD and the chest of drawers convo would be good. Mostly I want to know how he wasn’t functioning at home to understand the character changes.
I want more UK based stuff, more in depth about the characters families and more realism. Would love to see Molly interacting with Two Section. Her and Maisie would be double trouble in the best way.
Deal with the Lane CJ fall out. 
CJ getting help for PTSD and a real in-depth exploration of this subject. It’s a huge problem for Armed forces and many others. It deserved a platform to be explored and explained properly.
Fix Molly and CJ, realistically. Without compromising Molly characters or CJ’s.
Expand out on Georgie’s character away from her needing a man or going off piste in the most mad ways as plot devices. That’s getting boring and is unrealistic and while I might not be that fond of Georgie as a character, I thing Michelle is a good actress.
Ohh, having Corporal Geddings back would be a bonus.
If I can’t have all that, I’d go for a re-boot with a new Character as the female focus.
Must have BA whatever happens.
