Helen Crump wrote the screenplay for the movie, but Andy Taylor takes Aunt Bee and dopie Opie to Hollywood? Even as a kid watching this, I had to wonder about Andy. Was Gomer going to make a cameo appearance?
Aunt Bee was great in Mayberry, cooking dinner, making pies and pickles, keeping the house clean, etc. She was a great mother figure for Opie, and I always liked Aunt Bee. Unfortunately the writers made her character into a very limited person. Once she was out of Mayberry, all Aunt Bee did in the Hollywood episodes was to be a hillbilly over-reacting to everything she experienced. Aunt Bee deserved better than that.
I really feel like the writing changed after Barney left, and the writers did not know how to make characters like Aunt Bee charming, and they just focused on her being from a small town (Mayberry), so she seemed ignorant. The early seasons treated her much better, and she always seemed sweet, whimsical, and wise. The post-Barney years lacked that sweetness most of the time.
As a kid, I found these Hollywood episodes insanely boring. Walking around complaining about how everything was different from Mayberry, or how it really was in Mayberry, or why she missed Mayberry, Aunt Bee made 30 minutes seem like 3 hours. But that is due to the bad writing, in my humble opinion.
