Yes and no.
Being serious for a moment...
There's no doubt that RoS was a sub-par ending to the trilogy. But the first two films did very well and were very well received. There's always been a very vocal Star Wars minority that don't like anything post RotJ, they've just gotten easier to hear/harder to avoid with the rise of the internet and Youtube.
But Star Wars isn't just its movies. Disney has also had three very well received original TV shows (not including all the Lego spin offs), made the extremely popular decision to bring back Clone Wars, and is planning two further live action TV shows. Thats before we get in to their successful and well-written series of books etc.
Certainly I hope that after a couple of years off they deliver a more consistent experience with some mainline films, but generally speaking Disney has done a good job with Star Wars.
Of course bringing back once-popular series like Clone Wars is a step in the right direction. Indeed, there is success but I imagine Disney will forever wonder to themselves what could have been if things were planned out and done better. A 1.1 billion dollar movie with mediocre merch sales could have been a 1.5 or 1.6 billion dollar movie with better merch sales.
Now I understand they're looking to slow SW films production down going forward. This seems like a retreat to me.
As for Last Jedi being well received... Not too sure about that...
