I didn't know about mistakes in the visuals and I understood before I saw it that Aldrich Ames was the spy but I still thought this was well done. Just because you know the ending doesn't mean it can't be suspenseful. Anyway, I thought everybody was good in this show and I looked forward to the next episode. It beats the heck out of the junk on TV about amateur performers, morons getting dates, fat people losing weight and people falling off things. If you want something with a good story you usually end up on HBO or Showtime. I'd like to thank ABC for showing the remaining episodes. I appreciated that. Even if it was a weird time. You have to love timers.
