It shows 26 seasons available. I haven't looked at each season to see if there are episodes missing.
Indeed it does, but it stops there. The problem begins rather early too. Season 1 and 2 are complete but then check out season 3 for example. Only contains 3 actual episodes split in 4 parts each (normal) and starts at episode "The Ark" which is in fact the 6th episode in that season. The first 5 episodes are
* Galaxy 4 (4 part, missing entirely)
* Mission to the Unknown (1 part, missing entirely)
* The Myth Makers (4 parts, missing entirely)
* The Dalek's Master Plan (12 part, missing entirely)
* The Massacre of St. Bartholomew's Eve (4 part, missing entirely)
then comes "The Ark" then another missing episode
* The Celestial Toymaker (4 parts)
Then comes "The Gunfighters"
then another missing episode
* "The Savages (4 parts, missing entirely)
then comes "The War Machines"
and that's just 3 seasons into a 26 season classic series. It gets worse than that.
When you say classic Doctor Who, do they go back to the 70's/80's? I would sign-up for that alone. Thanks.
They go back all the way to S1, but as i said, their episode is anything but complete. Looking at my collection, and i guarantee you, i'm not missing a single episode. Not even the fan reconstructed episodes because the BBC burned footage, you're looking at 264GB in total.
That's not even accounting for the spin-offs of "Torchwood", "The Sarah Jane Adventures" and a shit ton more (including radio audio episodes i have) you're looking at a total of 544GB for that Show alone
