Well, everyone has there own tiers for ranking movies with different criteria. I always try to combine and mix the artistic part (the story, writing, performances, visuals, tone, sets, music etc.), the historical relevance and with my personal feel, experience, enjoyment, emotion of the movies, when rating a film. It doesn't matter what genre it is.
If i like the film and it has the quality to back it up for me, it doesn't matter, if it's a comic book one or not. I would rate it just as high as other genres. Logan, X2, Days of Future Past, The Dark Knight trilogy are in the same boat for example as Taxi Driver, Apocalypse Now, Psycho, The Usual Suspects, The Silence of the Lambs, Pulp Fiction etc.
My IMDB rankings are full of films, which have a 5-6 rating, but i have given them an 8-9, because i have like them in many ways. And the other side, there are those with a 7-8 rating, but for which i have given a 4-5-6 one, just because i haven't found them interesting enough. A bad film for one, could be a great film for other.
PS. Chernobyl is one of the best TV shows ever made. Simply outstanding.
Watched the first episode of HBO Watchmen and it definitely wasn't what i was expecting. Had so much hope for it, but surrounding it with the race history of America is an exit to the door for me. Didn't continue with it.
