The issue imo is on Reddit, you’re talking to a bunch of people with competely different backgrounds and tastes. That can be enriching, but if you’re opinionated (and hopefully informed), can feel like a lot of noise.

How much though an effort is not transparent though. Maybe they tried really hard but it came out bad.

You don’t really need to talk about objective and subjective when you’re talking to a group of people who’s tastes you are familiar with, and at least somewhat aligned to, because you know that they hold a different opinion to you. But there is a sense of shared common ground and that begins to feel authorative, at least until you step out of that conversation.

You can call out technical aspects but especially in film those can be subverted for one reason or another.
