As for “you weren’t there”, I think it is a much better line than “don’t lecture me Obi-wan” and given the context of TCW Anakin, it does flow seamlessly, the theatrical line is bad and feels out of place.
To me, it’s not the content of the line, it’s the fact that the audio and sound of the delivery does not fit with scene or Anakin’s other dialogue. Not fit in the story sense, but in the technical sense.
Sure, it makes sense for him to say that in the new context NFB has created, but I don’t think it holds up technically.
