Constructive criticism doesn't need to incorporate apologetic statements such as "I really love X, but Y." Constructive criticism is intended to be helpful by pointing out areas needing improvement.

Constructive criticism can also be blatant; sugar-coating is not required, especially since discussing AST's shortcoming in gameplay and suggesting improvement is not the same as bashing the designers and artists who made the Job. The true insult would be not caring enough to share candid feedback.
