Summary
An animated comedy series following the low-ranking support crew aboard the USS Cerritos, one of Starfleet's least important ships. Ensigns Mariner, Boimler, Tendi, and Rutherford handle the menial tasks of second contact missions while navigating their careers, friendships, and the occasional galactic crisis the senior officers are too busy to notice.
Star Trek: Lower Decks is a 2020 action, adventure and animation television series.
Rotten Tomatoes carries a separate audience for the same title, 272 of whom clear the calibration test. The cohort it is ranked inside is 2020s television series — 3,070 of them. The calibrated figure is built from 454 reviewers whose rating history varies enough to place their own average. A broader pool of 487 reviewers with two or more reviews feeds the raw-average track instead.
How the score was built
We compare the reviewers of this title against every other title those same people reviewed. Each review is scored relative to the reviewer's own baseline — a 7/10 from a hard grader sits well above their average, while a 7/10 from a generous grader sits below theirs. Every reviewer then counts the same, so the result is a calibrated consensus rather than a raw average.
- Global percentile
- Where Star Trek: Lower Decks lands against every title we rank.
- In-cohort percentile
- The same comparison narrowed to its cohort — titles of the same format released in the same decade. A 1970s film is judged against 1970s films, not against last year's streaming series. Ranked against TV Series · 2020s (3,070 titles).
- AI-adjusted percentile
- The same reviewer-normalized score, corrected for how much confidence the sample supports: thin samples are pulled toward the corpus average. Each title keeps the share n / (n + 53) of its measured distance from the average, where n is its calibrated-reviewer count, and the result is ranked on the same scale as the global percentile.53 is the median sample size across everything we rank. Here n is 454.
