I remember at least 10 matches from the 3 hour Raw 2 weeks ago and barely a single promo as compared to the usual, what, 3 matches and 6 promos?
The advantage to this method too is that far more superstars are naturally utilized for the 3 hour shows so I can not only see Smackdown people which I probably wouldn't otherwise, but them vs. Raw people instead the same 3 matches over and over and over again.
3 hour shows every week would be overkill. Once every two months or something like that is fine. Sometimes the 3 hour RAW's turn out to be good, and sometimes they turn out to be bad. A lot of the times with these shows one of the hours is completely pointless and
****.
