I'm currently reading Paths of Disharmony and I am enjoying the current TNG crew. It is not an issue of "the old crew is gone so it cannot work". It's a matter of if the replacement main crew can be well written and in this case, I say yes they can.
That may be the case for you (and for me, BTW), but there are others who do not feel that way. With only four of the original TNG characters left, they may prefer future TNG books to go back during the timeframe of the TV series or at some point prior to
Nemesis when the original crew was still together.
