I think there might be a spoiler somewhere...
I watched the original run between the ages of 9 and 12, and remember picking up on Julia's unrequited feelings, even though I didn't really understand it fully. I just wanted Barn. to be nicer to Julia and get rid of all the other girls he was chasing, lol.
Watching it now as an adult has been a real treat, as I've been able to pick up on the nuances of the performances, and gain an appreciation for the talents of many cast members I'd overlooked as a kid.
I don't remember being scared by the show in general, except on a couple occasions...seeing the "popeye" Josette and Quentin's ghost when he was menacing David.
