Definitely agreeing on another ep dedicated to Betty as a main character. Just to see her full persona on a normal basis beyond "prettiest girl in school", & if possible her family life, how she sees the main characters, just developing her up to main char status developmen-wise.
An episode fully detailing Cindy's (& maybe a little of Libby's) family life. I mean we got all 3 of the guys', so why not the girls + Betty? Only fair after all.
I would've liked a movie with the gorlocks showing a visit to their planet in a time of crises, or similar. Not nessacarily J/A, but I suppose it'd be inevitable. Nice switch for Cindy's jealousy instead of just ONLY at Betty, but rather any girl the guy's attracted to. Maybe then it'd be less of a problem for J/B fans on sites like ff.net if its was shown as more of a general thing, & more than the two girls had a decent, realistic chance at Jimmy's heart.
One or two more focusing on S/L, they barely got 3 or so total eps centering them, if that many.
Something with Sam Melnick as one of the central characters. Dunno why, but he was usually in my top ten after the main 6.
