I thought the first two books were enjoyable. Certainly there were better books in the series, but I thought they were both solid. For me the characterizations were spot on and I could easily picture the characters saying their lines. So I don't think their the disasters some have made them out to be.
I'm with you. I enjoyed seeing Wesley the Traveler back, and I had no problem with Colleen Cabot - she'd hardly be the first person to let her professionalism slip when she falls in love. I liked never being sure if she was intended to be a new regular (knowing that Picard would eventually be in need of a new counselor), a recurring guest or a red herring.
My only (slight) annoyance was the total lack of faith the admiralty had in Picard. Not too many of them were prepared to go into bat for a man who'd proven his loyalty many times over. But then, the books were supposed to make us frustrated, and sympathize with Starfleet's treatment of Picard and Data.
