As mentioned above, I'm referring to the content on the channel itself outside of a race weekend. Take the review of the year, that wasn't even available unless you had Sky Sports last year as they binned it for the Darts. There's also stuff like the Legends of F1 (as El_Watcher says) and other extra programming that just isn't made anymore.
As for the race weekends, there's more adverts since BBC went, more fillers and less interesting sections in the shows. The majority of it is just the three pundits standing there discussing irrelevant things. The race on Sunday was very busy but little of it outside the first lap was even discussed.
Its a shame as in the first few years it was genuinely good.
