My take on "Repetition of the Daleks":
It was pretty.....average, overall. Some good scenes, some great set pieces (the Daleks zooming in to the Tardis), some stuff that left me scratching my head afterwards.
One complaint about Ryan - when he was introduced, it was made careful note that he had an unusual medical condition that made him awkward and clumsy (thus his problems riding a bike). But at no time during his tenure can I recall it ever being mentioned again! This was an EPIC FAIL of the "Chekhov's Gun" Principle! For all the attention given it, he might as well have had "cyclophobia" - fear of bicycles. His getting back up on the bike and having another go in his final scene would have then represented how his travels with The Doctor gave him the confidence to tackle his fear head-on.
Well, at least Graham got to leave on his own terms. I'm trying to think of other Companions who left of their own will and on good terms, and there haven't been many of late....
