I guess you can objectively talk about technique in media and art and what it does in conveying the message. Critics have to decide if the work is good or not. That's pretty subjective but you can talk about how technique is used and whether it serves the vision of the work. Critics have to explain why they like or dislike a thing. Objective analysis may help convice a reader of his/her argument. The measure of the work may be the end result though and not the skillfullness of the technique used.
