I wouldn't say it's lazy. I'd call Channel 4 lazy for rerunning the same 4 Block Man idents continually for the past 4 years or so. It'll be nice to see them again randomly!
They've been on air for 26 months. Hardly four years...
Oh I don't know, I come from a time when a globe on BBC1 would spin for years. No variation, no music behind it... just a globe spinning for years.
