Do you think the life lessons were too heavy-handed?
In my opinion, GMW's biggest flaw was the way life lessons were handled in most episodes. Too often, it felt like the writers tried too hard to drive home a point or moral, rather than letting the storyline flow naturally. This was often done with characters repeating the same line throughout an episode to the extent that the dialogue felt unnatural. One exception I can recall is "The Forgiveness Project." That episode, I didn't feel like the theme of forgiveness was excessively driven in. However, with some of the same writers from BMW also working on GMW, I expected better writing for the series overall.
I know the show wasn't meant to be a carbon copy of BMW, but with that show, the life lessons felt more organic to the story and even if a moral was "revealed" at the end of an episode, it didn't feel like the writers were beating the audience over the head with it. It's like the "show, don't tell" rule of writing. Girl Meets World told the moral of the story (repeatedly), while Boy Meets World showed it.
That said, I enjoyed GMW but wish it could've had more time (or another network) to allow the show to further develop, and I wish the writing hadn't talked down to the audience so much.
