I thought that was laugh out loud excellent. The script is good, and there's massive acting firepower being deployed to cover the gaps. It's obviously going to have a Rising Damp air to it before Ms La Tour arrives on set, and you don't have to have seen Sir Ian's Estragon (which was fabulous) to see the Godot aspects.
The weak points are the wildly inappropriate theme music, which appears to have arrived from another series, the dirt cheap exterior shots and a nagging suspicion that the rape jokes were pushing it a bit. But overall, fabulous, and well worth watching next week.
