Is it worth continuing?

Hello. I have started to read LN, and my first series is Monogatari. I baught them all (got a good prise) and have been reading then without a different book between the books.

Now i loved the first 4 books. They had good story and funny dialog. After, it got a more draged out and boring. I'm on Kabukimonogatari now and kind of done with it.

After nisemomogatari i have been forcing myself to read them ans not found them intereating ar all

So, is it worth continuing?
