IMDb users are particularly fond of Episode 12 of “9-1-1: Lone Star” Season 2. The episode, titled “The Big Heat,” holds an impressive 8.9 average rating out of 10 on IMDb — making it the show’s highest-rated installment to date. As of this writing, that’s based on 466 user reviews. Meanwhile, “Saving Grace,” the ninth installment of “9-1-1: Lone Star” Season 2, currently ranks as the show’s second-highest rated episode with an 8.7 average rating out of 10 (via IMDb).
Looking at both episodes, it’s not hard to see why “The Big Heat” holds a higher score than “Saving Grace.” Picking up where the show’s previous installment left off, with Rob Lowe’s Owen unconscious in a burning building, “The Big Heat” is an intense and truly unpredictable hour of television. Not only does the episode see Owen get arrested under suspicion of being the very same serial arsonist he’s been investigating, but it also brings its central case to a shocking, unexpected, and brutal conclusion. In case that wasn’t enough, the episode’s final act also hits viewers with an additional twist that injects its final 10 minutes with an unshakeable level of tension.
In other words, “The Big Heat” is an episode that definitely deserves to sit at the top of most fans’ “9-1-1: Lone Star” rankings.
