Two things I loved about the prequel’s were General Grievous and all the extras George put on the DVD/Blu-Ray. I really think that was one of the great things about Lucas in that he loaded his stuff with extras. TFA Blu-Ray had pretty much nothing. I had to also buy the 3D version to get a few extras that wasn’t on the original Blu-Ray, but it still wasn’t worth the $30 to buy that movie again.
I really hope with TLJ that they bring back all the extras and things. I don’t like the prequels, but did enjoy all the extra stuff that was included on the prequel DVD/Blu-Ray’s.
