    Wow

    This episode was very intense on all fronts and absolutely outstanding. Very enjoyable, huge developments in the story, season 3 is definitely getting even better now.

    Maybe the best episode of the entire series!

    Wow, S3E4 is an incredible episode that turns up the dial on what started out as a slow burner of a season. With bits and pieces of the main story arc fed to us in the first 3 episodes, everything comes together for an absolute thriller of a ride in this episode! The ending gave me absolute chills, can't wait to see what happens next!

    And Stranger Things is Back!!!

    This reviewer was concerned after episodes 1-3. Very concerned. Then "The Sauna Test" brings the full fun of watching Stranger Things back Full Force!!

    Getting better

    Like both the previous seasons, First three were setting up the plot, now the cards are open we can gave the showdown. But the only complain remains still about non realistic interaction between the characters.

    Development matters

    Other reviews of this episode mention how good it is due to "character development, music, etc..." but then say how much better it is than episodes 1 & 2. These episodes were used to set up the rest of the season! We all know these characters so well, but time has passed since we've seen them. The writers couldn't just jump into the next encounter with the Upside-Down world without giving us reasons to continue to care about these kids. I think they did an excellent job of creating some division among the group, all while setting up the pending danger. This is the first clear sign that "Stranger Things" continues to reach the bar that it has set so high for itself.

    • Goofs
      In season 3 Max and Eleven were talking about the Wonder Woman comics. Max incorrectly states Wonder Woman's identity as Princess Diana instead of Diana Prince. Wonder Woman's identity is Princess Diana. Her "secret" identity is Diana Prince. Either would be correct.
