You don't see any other 'long running prime time weekly episodic television show' (or whatever it is they call it these days) spending 40% or so of their run time covering the previous episode. At most it's like a minute or two of "Previously on INSERT SHOW TITLE HERE", before the opening credits.

Personally in this day and age where everything's available anonymously over the net, if you put a little thought into accessing it, I can't see why anyone watches Raw live.
To my mind the best way for the WWE to get ratings for Raw, and the associated ad revenue, etc, etc, is to make Raw as immediately must-see as possible for all the Twitter geeks out there, which means interactivity and unpredictability (i.e. the Raw Active thing, multiplied by 5, with legitimately determined choices between truly different options – Streetfight, No DQ, and No Holds Barred won't cut it).
It means making the show so compelling and so interesting and exciting and complex that viewers want, nay NEED, to discuss it in real time during the broadcast.
What they do at the moment just won't cut it in the long run these days. Heading in the right direction in some small, slight ways, perhaps, but nowhere near enough.

That Raw was awesome. It was the lead up to the KoTR PPV and it had Brock vs Booker T, nWo with HBK was there and I think it was the event that had Undertaker vs the Hardy’s…or maybe just Jeff in the ladder match for the title. It was in Oakland in 2002, awesome show
