Okay, I know this has been discussed ad naseum, but the fact I have to completely reset my Apple Watch just to update it is a bit sad. Come on, Apple.

you aren't crying loud enough. if only these updates could be instant so that you can go back to scrolling through random pictures on instagram
I don't do Instagram and you can't do that from the watch. My concern was that the watch was frozen as it's been over a half hour.

I tried a hard reset which didn't work. I then used "Find My" to send a sound to the watch and that brought the watch back to normal.

And THIS is why I posted. Not to complain about the time it takes, but to see if anyone else has any issues.
No issues for me updated all iDevices...Phone, Pad, Watch. All went without any issues.
