The US version was severely bungled, especially in the cutting of the runtime to a 30 minute timeslot from 60. They made that decision AFTER filming it, so they edited down full episodes to half their length.
I think everyone agrees that Reggie Watts was not a great choice for the Taskmaster, but I do think a US version could work with the right group. It has to find it’s own voice though, and be given room to grow, which is hard for US TV.
