This is after watching all three seasons, the movies and also the manga.
I really enjoyed bungo stray dogs! It was an interesting start, and things were a bit slow on the uptake, but the anime progressed really well, and it's a somewhat light angsty supernatural action anime that some love. I think the thing that puts people off is how slow it progresses at the beginning, and that's why some drop it but then again I'm not really a justifiable source so ignore me.
The main reason I didn't drop the anime was because I had already seen clips and reviews of the anime beforehand, and was interested in the characters more than the overall plot. Basically, if I hadn't seen the videos beforehand, I probably would have dropped the anime too.
It is a good anime though, and I recommend it if you're looking for something light but dark at the same time.
