It seems that Alix tended to see things in black and white and in that sense she was not complex. She was not a stupid woman by far but she was not an intellectual and did not have the inclination or the ability to evaluate people and life in a complex way. She seemed to think "what you see is what you get" which is a simplistic way of looking at life. So in that sense, yes she was quite transparent and not complex. On the other hand, we only know this from reading her diaries or from what others said about her and not first hand, so who knows what she was really like....
