Apparently Christopher Ecclestone is scared of being typecast. He shouldn't be. He's a good enough actor that it needn't happen. Anyway. The New Dr Who looks good & it would be a shame to make a strong restart and then burn through a regeneration after 1 season just because...

We were already deprived the McGann-Ecclestone moment, (just as we had, incidentally, been deprived the McCoy-McGann moment.... wasn't that an actor in a Sylvester McCoy wig?) & he only has 12 lives, after all.... Stick around.... Make some more episodes.... Save the regeneration for another time.
