As a 29 year old I Grew up watching the original and really liked it a lot and was interested to see how well the reboot was going to be. With Kennan Thompson being an executive producer and a few other original cast members getting involved and showing the new kids the ropes and giving them tips I'd say show is gonna do well.
The fact is the target audience for the show isn't the 30-40 year olds that grew up with the original. It's for kids and they are going to do sketches aimed at kids. We have SNL for us adults.
People need to give these kids time. It's likely their first acting job much like how many of the original casts first acting job was all that and don't put the blame on what the writers wrote for the Sketch. The kids are in good hands and with time they will grow and be successful. V
