Doctor Who: The Forgotten #1 is a deft mix of fan service and compelling premise, of compressed and decompressed storytelling.
It starts off in a museum full of artifacts from the Doctor's various adventures, rather like the first-season Dalek ep of the current series. Then they find a room full of the Doctor's previous costumes and artifacts, and treat the Sixth Doctor's Coat of Many Colors with the derision it deserves. (There's even a shoutout to Shalka, if I'm not mistaken -- when Martha points out #9's outfit, the Doctor responds, "You should have seen what I ALMOST wore.")
From there, the premise is compelling but shaky -- a mysterious shadowy figure turns a dial and somehow makes the Doctor forget everything prior to his most recent regeneration (except a few details like the Time War). Martha gives him #1's walking stick, which helps him recover his memory by telling a black-and-white story-within-a-story set somewhere in the earliest days of the series, some time prior to The Aztecs.
And this is what I meant about compressed versus decompressed storytelling -- here's a book with a two-page spread that just shows the 9 previous Doctors' costumes and artifacts lined up, which then turns around and tells a complete, satisfying First Doctor story over the course of eight pages.
The end of the issue still has the Doctor mostly-amnesiac, and the Mysterious Shadowy Figure hints that he's a Time Lord and we can see he's got a goatee. Maybe they'll try and throw a curveball and have it be somebody other than the obvious, but for now I'm going to safely assume it's exactly who it looks like.
Of course, the Master showing up here begs its own set of questions. I'm going to reasonably assume that this is an earlier version of the Master (partly because the comics are non-canon and wouldn't bring him back after the end of season 3, and partly because this story chronologically takes place before the end of season 3 anyway), but that still requires some reconciliation with the whole "last of the Time Lords" bit -- are there other Time Lords still bouncing around time, "before" their deaths in the Time War? Did the Doctor just never expect to meet any? Or is this just made possible by the fact that the Master is still alive at the end of time, and is the story going to try to accomodate that by having him get away without the Doctor seeing him?
Anyway. A decent setup -- we've got a decent premise, we've got loads of fan service, we've got Martha being competent (and only briefly whining about Rose). But #2 is going to have to ratchet things up some. We're going to have to find out what the Master's plan actually is, how he managed to make the Doctor forget his previous nine selves just by turning a dial, and it would be awfully anticlimactic if the whole issue were just #10 sitting in the museum telling stories about #2 and #3.
All in all, good comic, good storytelling techniques, good art. Pick this one up.
