User blog comment:MalXXxX/Is s4 worth watching?/@comment-27794543-20190716061204

I'm not sure how to answer your question without giving you a lot of spoilers. There are several significant character deaths, so if you like those characters, this is your last opportunity. 410 is a battle royale. Season ends with new groups formed and old groups dissolved/absorbed (which is important setup for s5). Can you watch s5 while skipping s4? I guess, but you'll be missing some significant details.

I enjoyed s4, so obviously I'm biased. I don't know where you read which season are terrible or amazing, but those opinions vary quite a lot. There's plenty of people who consider s5 the worst season, so don't assume it's going to be 'amazing' for you (especially if you skip s4 and then confused by what's going on). Maybe you'll love s4, maybe not; maybe you'll love s5, maybe not. No one but you can decide that for yourself.
