I don't think the concept of an 8 year old boy love crushing on someone like Frankie is anything that is considered "wrong". Nancy Callahan hit on a guy old enough to be her grandfather in "Sin City", and Vash the Stampede was REALLY in love with a much older woman in "Trigun". This really isn't a big shocker.
I think the thing that worked here is that this episode (along with the last line of new ones) have been switching gears and changing things before we know it. They take half of the episode in one direction then before you know it, BAM! Your in a new direction. From Mac, Bloo, and Frankie, to Bloo running around.
Episodes such as this one prove that this show can still pull off a trick or 2 behind our backs. Just like with "Schlock star" I was totally expecting Bloo to become the jackass he usually is and make his whiny selfish attitude the focus. However, they switched it around with the band taking him in and etc.
Especially with Berry's return, I think it's safe to say that these new episodes are breaking lots of barriers in predictability, and it's almost impossible to tell which character will show up and what twist the plot will take. For example, I expected the rest of the episode to have Bloo trying to botch Frankie and Mac's date.
Instead, they decided to remove Frankie and Mac to the house, then switch it to Madame Foster and Bloo THEN Jackie Khones and Bloo and so on and so forth. They kept me guessing and laughing at the same time and it's a formula that I think works, and I also hope it's here to stay because it is GREAT!
Plus, like Cass said........Frankie wore the black dress!!!
. I feel like Homer Simpson every time I see Frankie in it.
"MMmmmmm black dress.....*drool*
