This area is the western end of the Corridors and faces west. There are about 20 short, decomposing, very well bolted and fun sport routes. My guess is the cliff is 30 feet tall and fixed anchors to lower off are always nearby.
The majority of routes are steep technical face climbing, think fat edging between crimps on just less than vertical rock. Despite the rain of choss that will be coming down from the leader, the tight bolt spacing and fun moves could make up for it.
The cracks did not seem worth the effort, but they may improve with time.
These routes are in a rapid state of evolution and you can expect ratings to vary greatly over time.
This area is the west side of the Corridors, in the Cattle Pocket basin of Movie Flat Road. The best approach is to park at the east end of the Corridors on the NORTH side of the dry creek bed and follow a short, well marked trail west.
Mountain Project's determination of some of the classic, most popular, highest rated routes for Sunday Matinee Wall:
Because this is a narrow corridor, the risk of falling backward and "heading" into the opposite wall is pretty high if a rotten hold breaks and your belayer is keeping you loose, trying to get grains of granite out of their eyes.
I saw this happen in early April with no drama thankfully. Helmets and eye protection (sun glasses) for your belayer are strongly recommended in this area.
