I hope they show more Reva. This was just her first appearance. Tons of characters were disliked before getting more character development. Ahsoka was initially hated. Ezra was initially hated. Anakin was initially hated.

Also this is one of the few cases where we can see a dark side user come back to the light and not immediately die after. I'd love to see what she does after this.

I also enjoyed the actor's performance when she played the "good" Reva. I felt her portrayal of "bad" Reva was too try-hard. I know that sort of tracks with the character since Reva was never really a bad person. Her bad persona was an attempt to hide behind a mask and so her bad persona was supposed to look forced to the viewer.
