I am about half way through book 8. Reading this thread has made me reconsider however that maybe my opinion of his work is outdated, my opinion was formed primarily of Family Guy and American Dad which whilst they started off OK became pretty tiring pretty quick with constant repetition of things that weren't even funny in the first place like that chicken fight crap.
I will still look forward to the DCC adaptation for what it is but in the mean time I think I will try out some of his other work I haven't seen to see if my opinion changes and can be updated as from looking at the dates Family Guy was over 25 years ago now which instantly makes me feel even older too!
