You can't give Dredd a 9 since Aliens or Robocop which are clearly MUCH better films can get at most a 10 (99%)
This is not an opinion this is a fact.
Film taste is fucking opinion you bellend. Who gives a fuck if somebody else gave Dredd a 9/10, they may (heaven forbid!) like it more than Aliens or Robocop, and if you don't like it (that's fine) but it doesn't make them wrong. That's fact.
