IO9 has a non-spoiler review up of the super successful Netflix series which is set to debut season 3 later this week. The review is pretty darn good.

After every episode of Stranger Things 3, you’ll find yourself eagerly skipping the credits to jump into the next one. So, in that way alone, the new season works. Almost all of the characters get denser storylines to play out. The action is exponentially bigger than the previous seasons. It’s funny, gross, sweet, and fun, and by the end, the whole thing gets so massive and exciting, you’re likely not to remember a few of the hiccups along the way.
