I only recently discovered the interviews in question, and I've been popping in between panic and uneasiness. Mostly because you don't really see it in any of his written episodes (excepting maybe Girl in the Fireplace) and I've been wanting to give him benefit of the doubt.

But I completely agree about the the continuity issue; if he's helming S5, I'd actually also prefer Tennant to quit. Moffat doesn't have the greatest track record with Doctor/Companion interactions and issues (we'll see what he does with the newest two episodes he's penned) and since this is as much as the Companion Show for me as it is the Doctor Show, I'm a bit worried that it'll bleed through.

I suppose it's possible that we'll revert to Classic Who? Stand-alone episodes with seasonlong storylines relegated downward?
