Dagon is young yet, and his attention span is suitably non-existent. We've watched a lot of movies, but generally he is completely disinterested in what's on the screen.
The sole exception to date is Sheri Moon Zombie. We were watching House of 1000 Corpses, and whenever she came on and said something, his ears perked and he jumped on the desk to get a closer look.
It appears he loves Sheri Moon Zombie.
To test this theory further, we watched Devil's Rejects and the remake of Hallowe'en (ew). His reaction was the same, so the theory stands.
Dagon loves Sheri Moon Zombie. Awwww…
