Query: Bad, boring read!

For somebody who has read all of Patrick Robinson's work, I was thrilled with Nimitz Class, and emmensely enjoyed Kilo Class, liked the first half of HMS Unseen. From there on, it was a downhill run. Mr Robinson should clearly start writing about something other than submarines. Compared with his previous work, the plot is unoriginal, thin, and the characters boring, and hardly developed at all. In fact, his imagination was so strained that has re-visited topics raised in earlier works. If you want a really good read, pick Nimitz Class or Kilo Class. The rest are rubbish.
