I must say that 2005 was probably the best (although not many people would agree with me on that). But Dimbleby was on-form that night - the best BBC election night coverage of the 2010's aside from 2019 for me.
I would agree that 2005 was my favourite election coverage of the century- a great team of David Dimbleby, Peter Snow, Jeremy Paxman, Andrew Marr and Tony King, and a brilliant set, with all the "windows" overlooking Shepherd's Bush and the numerous shots of TV Centre. It was also probably the last election with umpteen reporters and the likes of Adrian Chiles and Lizo Mzimba being pressed into service, and of course the last one with Snow and King.
Dimbleby was in particularly playful mood and there was some great stuff with Paxman as well, the Galloway moment is the famous one (and everyone forgets as soon as it finished he turned to David Lammy and took up completely the opposite argument) but there was also some great chat earlier on with Shirley Williams and Lord Falconer having a really good-humoured argument about postal votes, and Boris Johnson, funnily enough, saying it was brilliant it wasn't a Labour landslide and then trying to explain he didn't mean it like that.
Also it was probably the last "boring" election where we came out of it pretty much the same way we started, so it was all about the fun and excitement of election night for its own sakes and the graphics and the chat and so on. Unfortunately that's the reason why everyone's forgotten about it and so it won't get regular repeats, but 2005 was a great election on the Beeb.
