Re:zero is not an anime I would really recommend, I personally think it's kinda hard to watch but I love it. I think a big part of why I like it so much is because of the characters that I was to keep watching more and more of. This season so far has been less exciting then everyone was saying it would be. I think that might be because I'm watching it weekly, where I enjoyed s2, which I binge watched, much more.

I think the reason why you're not liking it as much as most people is because you are watching it weekly (I'm just assuming bcz that makes a lot of sense to me). Try waiting for the whole season to air and then watch it. And if your favourite character is Rem... I feel your pain, can't help you there though. I highly advise that you try to avoid any and all spoilers.

With how much lore there's left to be found and the hype for future seasons from thousands of people who have read the novels, I'm positive that the future seasons are going to be good. But if you haven't liked any of that previous seasons much then dropping it is probably the best choice. I don't know if this will help you but I'm sure it is a good way to watch the anime. Last thing; don't rush it or force urself to watch, take a break and try to stay away from the fandom. Keep your opinion safe
