First time watching - should I keep going?

Hello! I have been watching Pretty Little Liars for the very first time. I have been loving it! I have been so locked in during season 1-4.

I am now on season 5.... and I'm tired lol It's becoming a bit of a slog. It's gotten a little old. Everyone has only gotten dumber.

I keep seeing online that everyone agrees that 1-4 is the best and that 5-7 is tough.

Should I keep plugging along and push through? Is there enough good on the other side? Or should I give in and just look up season synopsis or give up completely?

Give a girl some strength and hope to keep going. lol
