By default RottenTomatoes pages uses base 10 rating for TOMATOMETER and base-5 for AUDIENCE SCORE. This script changes the latter's base-5 to base-10, and modifies both relevant tooltips, in order to be perceived more easily. It modifies these 3 elements:
multiplies x2 the AUDIENCE SCORE Average Ratings,
appends (=6 stars or higher) to the TOMATOMETER descriptive text,
modifies3.5 stars or higher to 7 stars or higher, in the AUDIENCE SCORE descriptive text.
Note 1: this script uses the setMutationHandler function (by wOxxOm) Note 2: after the new rottentomatoes.com layout (Feb. 25, 2019), since v4 the // @run-at document-start rule is no longer needed.
Thanks a lot to wOxxOm: he initially wrote it (v1) and he also offered improvements (v2, v3) and v4.
