I hate Terminator 2 so there you go 😄
It is a shit film
You might not like it, but it absolutely and unequivocally is not a shit film.
Not liking a film and film being a shit is the same thing.
Saying “A film is shit” and “I think this film is shit” or “In my opinion the film is shit” are completely different statements. The former is an objective statement while the latter two are subjective.
Film is an art and therefore completely subjective in the first place. Therefore, all there examples you gave are the same. The first one just skips the obvious thing, which is that the film is subjective and only subjective measure can be given.
