I agree partially. Lucas does deserve blame for structuring his trilogy badly and barely showing Anakin being heroic and likable or Anakin and Obi-Wan being friends. The only time we see Anakin be charming, likable, having a good rapport with Obi-Wan is the beginning of ROTS which is far too late. You have to sit through one boring film and one abysmal film to get to it.

But when people say TCW Anakin is a completely different character or that Filoni fixed him, it isn’t really correct. He’s the same as ROTS Anakin, we just got to see more of him.
