I have enjoyed this series - it tells the tale of a teenage mutant dealing with expectations of adult society (more overtly, with the reputation of the old Cable to live up to). It is light and refreshing, yet it plays nicely with Hickman's overall X-men direction and could only exist in Hickman's X-universe. In contrast, Wolverine's solo series is largely disconnected from the Krakoan nation at large, and could have existed in other X-men era's with only slight modifications. The events in X-Force largely go unreferenced/aren't connected to other X-series either.
I don't understand the impatience to bring back the original Cable. Even if Kid Cable isn't your cup of tea, all it requires is patience to wait for the return of old Cable, and soon enough it will just be another rehash of the same Cable stories (Cable vs Stryfe).
