That's a great analysis, Middy.
Frankly, there's a tendency amongst creators to fall in love with their work and it's difficult to get and maintain the necessary critical distance from it.
It's good to challenge every scene. Why is this scene here? Is it advancing the plot, illustrating the theme, telling us something about the character AND is it entertaining? Ideally, it should be all four of those things. That's very very hard to do, but it's a goal you have to aim for when writing for film/TV.

The hilarious play "Urinetown: The Musical" nails it in this exchange during the opening scene, titled—appropriately—"Too Much Exposition":

Everything in its time, Little Sally. You're too young to understand it
now, but nothing can kill a show like too much exposition.
How about bad subject matter?
Or a bad title, even? That could kill a show pretty good.
A good rule of thumb is to ask yourself, "Is this information for the audience's benefit or the character's benefit?" If the former, you're not doing your job right.
