“Shows like this “Saturday Night Live UK” aren’t and never have been my sort of thing: too noisy and forced.”
The studio audience had clearly been told to crank up the volume to 11. 
The reviews have been mixed to cautiously positive, which I think is fair. I honestly thought it would bomb but it was better than that.
As with the original SNL, not everything worked. I think that is particularly the case for sketch type comedy and topical humour. But the cast are all accomplished performers and some of the sketches were quite funny. Enough to make me watch next week anyway.
It might be a better test for the show next Saturday. Tina Fey, as an SNL veteran, was a strong opening night host. Will any of the other hosts be able to match her?
