Feeling or showing no admiration or interest in something.

Unimpressed → It is formed from "un-" (meaning not) and "impressed" (from Latin "imprimere", meaning to press into or stamp). The word "unimpressed" means not feeling admiration or interest, as if one has not been stamped with a positive impression.
Think of 'not' ('un-') feeling 'pressed' or 'stamped' with admiration — that's why unimpressed means you don't feel impressed.
