No. Good critics do not clutter up their writing with "Hey! That's just me! You may disagree, and that's OK!" and the like. It is understood that your review or essay is the distillation of your education, viewing, taste and temperament. That's what criticism is.
Film Critics should say it: Your own experience at a movie is NOT an empirical measurement of the universal correct reaction to it.
Film critics should talk about how much taste, temperament and expectation make a viewing experience singular, not universal.
