Cool idea!
I loved "Frankie My Dear", probably ties for my favorite Foster's eppie (along with "Squeeze the Day"). What do I think could have been improved about it? Toughy... But when Mac and Bloo are throwing the wads of paper at Chris, the papers are littering the floor, yet Mac says "Bloo, we need more amo!" And Bloo turns over the empty boxes that once held the documents and says "We're all out", I just didn't understand why they couldn't just pick all those papers up off the floor and throw them again. It would have been just as funny I think if they hadn't run out of "amo",
and it would have made more sense.
An episode I didn't like so much was "Emancipation Complication". But one thing I actually liked about it is we see Madame F.'s caring nature and how much she really cares for all the friends. And she DOES have some morals. For some reason, in some other episodes, she's not so much. I shouldn't have to name which ones they are.
She seems to be able to turn her conscience on and off, and in "EC", her conscience was obviously in the "On" position.
