As you say, the editing with the flashbacks did make it a choppy mess, and hard to get your bearings, but, I enjoyed it for the most part, though it did start to drag on "Sand World"
I think one reason it's hard to get your bearings is everyone is wearing the same clothes since it's all taking place on the same day!
In my first watch through during First Run, Greer was at the top of my "Space him now" list, it wasn't until the episode in S2 where they are trapped (Via stone-travel) on Earth in the Bunker that I was able to start appreciating him, and I enjoyed him more each episode thereafter. In my rewatch of the opener, my feelings haven't changed, he still annoys me in a bad way, but, at least I know his character gets better
The one I hated was Wray. Greer has some subtlety to him, though it irks how unprofessional he is. Guess you could say that about the whole lot though. I just enjoy Greer's passive aggressiveness.
Yea, Wray and the Colonel, Rush, Greer.
Most of them became better written/acted (IMHO) late S1/S2

Where are we going? And why are we in this Handbasket?
