The build-up is pointless, I rarely watch it. You don't know if the commentary will be dire, it can't be worse than what they have now. Do you know if there will be masses of adverts? The football manages with all the adverts before and after with a break at half time so why not have that for the F1? There are as many in replays during the race it is pretty difficult to miss any of the coverage.
They ,maybe do more than ITV, but sadly most of it is sheer rubbish so I can live without it.
With regards to the commentary being dire, I've found that, generally, any 5-produced programming has been a joke. Unlike football, Formula One doesn't have an interval in-between halves, so it's much harder to fit in a scheduled advert break. This means that the channel would have to fit them in throughout the whole race, something which caused problems with ITV (Imola 2005, anyone?). I would much rather not have any, but even ads similar to those we had on ITV would be preferable to what is seen with the IRL or cricket on Sky, which is just ridiculous: there's almost as much in the way of ads as there is action!
As for the rest, I really can't agree, personally. The BBC have done some very good in-depth features on regulations, technical aspects of cars and how teams operate over a race weekend, which have been insightful. Track guides with the drivers are enjoyable as they allow us to see how they approach the different corners, what they can do to gain or lose time and whether or not there are any benefits to attacking in different ways. Interviews with drivers are also nice to see, as it helps to convey the emotion behind their words far better than printed media does. I'll gladly admit that some build-up features have been quite pointless, and that Eddie Jordan serves little purpose, but overall the quality of the programme is high.
Commentary is getting better with every race, Martin Brundle is finding himself more comfortable in the lead commentator's role and DC is very quick to spot things on-track and pick up on things that Martin misses. My one criticism is his Red Bull bias, but he is still under contract with them, so I wouldn't expect him to be totally free from it. Coverage of practice sessions is far better than it has ever been; until 2008, we didn't even get that. ITV's 2008 coverage of practice was just a camera feed. You got no commentary, no analysis of what was going on etc. and it was quite boring. With David Croft, Maurice Hamilton, Anthony Davidson and Karun Chandhok, you get a very laid-back but informative approach to the sessions, which is perfect for a lower-pressure part of the weekend where the action is less significant.
Finally, having any real kind of post-race discussion (in the form of the forum) is appreciated as it allows time for people to form proper opinions and go over the events of the race in detail, as well as bring us more interviews from drivers that we otherwise wouldn't have got.
It's something that is always possible to be improved on, but the BBC's F1 package is very good and by far the best we've ever been given.
