What people sayPublic comments from other sites
AI sentiment analysisAn AI model (qwen3:8b) rates each public comment as very positive / positive / mixed / negative / very negative (scored 9.5 / 8 / 6 / 4 / 2), averages them weighted by confidence, site, length, “helpful” votes and date, then shrinks the result toward a neutral 6 (so a few comments can't inflate it).Calibrated to the site-score scale it is 7.25, and it counts toward the overall score by the number of comments (at most 35%).Only the latest ~40 comments per site are read (plus ~50 posts from each forum's episode threads, which weigh less): a sample, not everything. Excerpts are at most 140 characters and belong to their authors; comments that may contain spoilers are not shown. Comments from Chinese sites appear in an AI translation, with the original one click away. Sentiment labels can be wrong. Updated Oct 7, 2026, 06:36.See the score breakdownSentiment score6.2/10

Overall score The overall score is not a simple average but a weighted blend:
(w_P·P + w_T·T + v·R) / (w_P + w_T + v)This title: Site scores P = 7.90 (weight 63, 77%); Fan sentiment T = 7.25 (weight 18.7, 23%); Community: No ratings yet (each rating counts as one vote); P: site consensus 7.94 (16.9K votes), shrunk toward the season baseline 6.96 by vote count to 7.90.P is the consensus of site scores (calibrated to one scale), T the sentiment of public comments, R our community's mean. Each part is weighted in “virtual votes”: more votes and comments mean more weight.See the breakdown · Scoring rules in detailOverall score 7.8/10
Score breakdownThe three parts are weighted in “virtual votes”: the more site votes and analyzed comments, the more weight that part gets. Fan sentiment is capped at 35%, and each AniRanking rating counts as one vote. Full rules
- Site scores7.9077%Consensus of 16.9K site votes (calibrated to one scale and shrunk toward the global baseline by vote count)
- Fan sentiment7.2523%38 comments, average 6.28 (the sentiment score shown, 6.2, is also shrunk toward neutral), calibrated against comparable titles to 7.25
- CommunityNot counted0%No ratings yet (each rating counts as one vote)
Site scoresThe site consensus is 7.94 (16,851 votes, weighted by site reliability × log of votes); shrunk toward the season baseline 6.96 by vote count, it becomes 7.90. Sites score differently (Bangumi runs low, bilibili high), so each is first calibrated to one scale using titles rated on both it and AniList, then combined; sites with fewer than 100 votes are ignored.
