Anime where no scene is a waste of time?

Hello everyone, sorry to come off so hot. Truth be told, I can’t get enough of this stuff. I honestly find it more impactful than a lot of life hack/self-improvement content out there, which is a pretty odd application but i’m sure a lot of you could agree. Anyways:

I have watched around 20 anime series, a good blend of romance, isekai, and adventure. I love the normal structure of anime but I find that oftentimes the side characters play a filler role, and as such the scenes involving them can be draining. For example, Stein’s Gate had some of the best concepts i’ve ever seen in an anime, but Faris and Luka had absolutely no tension between any other characters making them feel flat. Additionally, the humor was extremely intermittent in a series as “good” as this one.

TLDR- I understand that filler and “husk” characters are a usual quality of anime, but ultimately I feel as though I lower my expectations for a lot of series to enjoy them. Is there a series out there that will blow me away every episode?
