It looks like when the system is retrieving the information from IMDB or rotten tomatoes, a lot of stuff do not match.
In example:
the documentary the battle of midway (https://unogs.com/video/?v=60027942) has in the rotten tomatoes tab 10 stars, but when you crosscheck it with the page (https://www.rottentomatoes.com/m/1051043_battle_of_midway) the scoring is not there, and the user rating is only 3.5/10

so the 10 stars appears from nowhere.

there are also plenty of examples with IMDB instead like this:
sand castle in your display: https://unogs.com/video/?v=80118916
sand castle in imdb : https://www.imdb.com/title/tt2582576/

thanks!
