Can a movie score 10 out of 10?

If not, why? If yes, why not 'Kashmir files'? From your description, it seems that no movie can ever score 10 out of 10 because if a movie sores that then you will write "Our rating mechanism has detected unusual voting activity on this title. To preserve the reliability of our rating system, an alternate weighting calculation has been applied." And downgrade it. Is your system reliable?
