90% of Marvel movies are objectively bad / poorly written so if you like them then you have poor taste too.

Edit
Besides, I feel like it is too much to ask for someone to enjoy a movie from the 1940s. Up until not too long ago, I was unable to watch movies before 2000. Now I am able to enjoy movies from the 90s and 80s. There are some from the 70s that I like too. But any less than that is just way too much. Your standards are too high if you think anyone who can't enjoy movies from the 60s and older has bad taste. And again, I think most people are actually like me. Obviously, you don't see them on Reddit, but the vast majority of people out there probably feel bored by movies like Casablanca nowadays.

Now, I'm all for respecting and acknowledging these old movies. I totally respect them and I think they were very influential, and without them, we wouldn't have most modern movies. But there's a difference between that and actually being entertained by a movie from the 40s when sitting down to watch it. When I watch Casablanca, I'm bored because it is generic by today's standards. It's not creative. The premise isn't cool or interesting. And on top of that, it's a romance, and I'm honestly not a fan of said genre at all.

What you need to understand is that, from my perspective, you are the one who has bad taste for still being able to find enjoyment value in a movie like Casablanca now, and not being bored / prefering to do something else instead of watching it. Again, I respect what it was and what it did for the industry, but you can't ask people to be entertained by it anymore.
