1x01 Pilot Part 2 [2nd watch]
[Watch it (again) on iPlayer.]
I somehow failed to note when I watched episode one of this season, which is a rather surprising oversight (I've now dropped it in somewhere that seems vaguely plausible). I thought I'd not made my comment on how they've finally changed the title sequence, something they've needed to do for years (ever since he took on a new team). Amusingly, they've done it in the cheapest way possible, dropping in new shots for the new cast names.
