Never read a Pratchett book in my life, started watching episode 1 last night but me and my wife found it a struggle.
If I didn't find anything in episode 1 funny, should I persevere?
If episode 1 doesn't sell it I doubt you will be into this material but episode two better represents the overall show IMO. If episode 2 doesn't do it then it is downhill from there really as you are almost to the peak of the show.
