Just started watching anime. How "happy" is this series?

I watched the first few episodes and did a little Googling, but I am trying to avoid spoilers. I've been watching a lot of Isekai lately, and have been drawn into ones that are more lighthearted in nature. For example I liked the one called something like "I've been fighting slimes for 300 years and maxed out my level." I also watched Re:Zero, but I found it too depressing for me.

So before I get too involved, what is the overall mood of the show? I don't mind some conflict and drama, but I like everything to be resolved on a good note.
