repeat footage? really?

i was kind of disappointed that they kept reusing footage (underwater wave shots, sharks eating albatross chicks, seahorses, easter island) in multiple episodes. they couldn't find a way to fill 45 minutes with all the footage they shot? seems amateur, not what i expect from the BBC.

i'm also a little concerned that since half the footage seems to be of the galapagos, the bbc series "galapagos" (next on my dvd list) will all be re-runs.
