The only thing that was rushed in TFA was the ending. And it wasn’t even rushed by that much.
If I were you, i.e. a defender of TFA, I would rather argue it was rushed. At least there would be an excuse why it is so bad.
The only thing that was “bad” about the ending is that Starkiller Base attack seemed like it wasn’t even pertinent. I was far more invested with what was going on with Kylo, Han, Finn and Rey.
