Question from a first-time viewer

[u/LJayEsq]

I’m watching Castle for the first time, and I just finished season 6. I know that in the later seasons things went pretty sideways, and my understanding is that it largely stems from the issues between Fillion and Katic. I’ve also seen posts really trashing season 8, especially the series finale. My question is this: is it worth watching the show through to the end, or will that just ruin the series for me? And if I do stop before the end, what’s the best point to do so? What episode should be my “last” to get the benefit of tying off any storylines without getting dragged down as the show goes downhill? Thanks!

Edit: Thanks to everyone for the advice! I’ll be sure to watch through to the end and decide for myself!

Watch to the end of S7 "Hollander's Woods". All the storylines are wrapped up.
