Should I watch s3-4 if I really enjoyed s1 ?

So I've heard of Killing Eve but never wached it while it was airing. I binged s1 on Netflix this week and honestly didn't expect to like it as much as I did. I'm definitely watching s2 since I've heard it's also a good season. But are s3-4 really as bad as I heard they are? I never read the books so have no idea what's gonna happen but I already got attached to the main characters especially Eve and Villanelle. Wouldn't want to get disappointed and I see that s4 episodes have really bad ratings on IMDb. Would you still recommend watching the show all the way through ?
