Spinner seemed annoyed to be at the 1:30 Friday slot. He felt a little punchy and was non-plused fans stilled wanted to talk about episodes of the TNG and hear stories about filming the show. Mainly, he did not seem sincere.
He did have funny moments. He had several good stories to tell, but preferred non-TNG questions.
Additionally, the other panelists were better, seemed sincere, really had thought about questions, wanted to be at the Con, etc.
