Ten people say it was great and one says it was mid, and guess which one you think about in bed.

Criticism sticks because your brain files it as a possible threat, and threats get priority. Praise gets processed as pleasant and then quietly released, which is why nine good comments can evaporate while one lukewarm one stays in the room all night. It is not a sign the negative one was more accurate. It simply had louder access.

Write the good ones down somewhere you can find them, since you will not remember them otherwise. When the one bad comment starts its shift, read the list. Then ask whether that comment held anything you could actually use.
