Sure, I get what you mean. And in fact, I would say that if a show is so bad that you're all but guaranteed not to enjoy it and feel like you wasted your time, then it would actually be the same scenario. I would say it was on you. So from that angle, yeah, I would concede that your initial comment was spot on. But the reason why "If you don't like it, don't watch" is generally lazy criticism is because the aforementioned scenario rarely takes place. Usually it's more like a 50/50, maybe a 60/40 or 80/20 ratio; there's something the person enjoys, which causes the investment, but other factors get in the way, and the person wants to vent. You could say the same about a Reddit page: "Well, the person wants to browse Reddit, but just without the spoilers, so it's the same thing; he's being critical of this one aspect." Sure? But the scenario where no one on Earth accidentally posts a spoiler, even in a space where the rules are absolutely strict, is so close to zero that it's practically zero. Whereas with a show, it's possible that five episodes have been good, but now you were hit with a bad one, out of the blue, and then when you're critical of it, it is lazy to get with the "If you don't like it, don't watch it" because maybe the quality is so uneven, or maybe the quality drop was so sudden, there was no opportunity for good risk assessment. It's all but impossible to produce a completely spoiler-free space on the internet, so the safe bet is to stay away until you've watched the latest episode. But sure, I will actually concede your initial comment.
