Yeah forgot about that. I really don´t know why Hackett debriefs him every fricking time.
In ME1 Shep has the opportunity to either inform the council after each main world (Feros ...) or NOT. So yeah he does not need to debrief with the council at all in ME1.

I think that Shepard should be able to command a Ship without Hackett telling him what to do every 20 minutes. LOL
Shep defeated the Sovereign without Hackett telling him what to do after each mission.
Shep defeated the Collectors without Hackett telling him what to do.
So yeah I think that they really overdid Admiral Hackett in ME3 !! Seriously ...
