One thing that I want to see a bit more of is Bol'daar and Geo's rivalry.
The series shows that Geo likes to snark on Bol'daar. But why? Was there some kind of resentment between the two?
In fact, there are other things that I'd like to see more of in the series. Most of the characters have some interesting backgrounds that Matthew for some reason hasn't added on to.
It's a bit of a shame how underutilized it all is.
