my rating standards:
5 stars: reserved for movies that are perfect (character building, acting, cinematography, use of music, intention/message of the author) AND/OR somehow resonate strongly with me and have me thinking
4 stars: outstanding movies
3 stars: movies that are either technically well done, thrilling or in any way relevant for either a country or overall cinema history, but lack in quality at one or more of the 5 above mentioned attributes
2 stars: movies that are ok
1 star: movies I found being a waste of time or I had to switch off
