A factor that needs to be taken into consideration here is that the show is still in its infancy (only a measly 4 episodes in, which were meant to set things up like the format, some of the character dynamics, etc.) and has some kinks to work out.
It can be easy to forget that The Muppet Show started out in a similar place before finding its groove. Its first season was spent doing a lot of experimenting, finding out what did or didn't work, tweaking the format, developing the characters, etc.
Also the fact that The Muppet Show was more gag-centric in the first season and became more character-based in the second season and beyond. The second season was also when the show's popularity truly began to kick in.
It seems to me that the new show shall go through a similar transformation as it continues to find its footing.
