Three hours is a long haul for any show, but RAW is the best that it's been in years from bell to bell.
WWE RAW used to have so much extra non-sensical shit. Everything is a major plot now more or less, ya know? I DVR it, and I don't try to finish it all Monday. If I do that's great, but I usually space my WWE out through the week so I don't overload.
EDIT: On OP's comments regarding his hopes for a departure of 3 hour RAW. It's USA's request that WWE have 3 hour RAW, WWE is simply fulfilling that request. There's no point in lambasting them for it.
