well it was mostly the writing. For one Matt's doctor was too similar to davids but he didnt have the same charm in my opinion. I would have liked it if he was more different. Plus the storylines confused me too much to the point where i lost interest but i might watch it from the beginning of series 5 to see if i can get it this time
I look forward to whatever you decide to use the Shalka Doctor in as a fancomic. As I probably said before, I really enjoyed this version even to the point that I roleplay him from time to time, and did a crappy drawing of my own a while back. Should do a new one sometime when I get the free time.
