The 22-episode second season of Lethal Weapon aired during the 2017/2018 TV season. Most fans know that the friction (to put it mildly) between Wayans and Crawford led to Crawford's firing and Riggs's writing off of the show. I will not spoil how the season ends, but needless to say, it ends on a very big cliffhanger.
Much of the season is devoted to Rigg's past, specifically at the hands of his abusive father. There are a lot of flashbacks throughout the season. Riggs still has guilt issues over the death of his wife, but the storyline that ended the first season (with Rigg's going to Mexico to get revenge) is resolved pretty much in the first episode. Two of Riggs' friends from his youth are brought into the story this season, one of which becomes a new love interest. I will not go into details to spoil anything for those who have not watched, but it follows the same formula as a weekly procedural that deals with the case of the week, with a larger story arc that spans the course of the season. This season's guest and recurring stars include Michelle Hurd, Ernie Hudson, Joanna "JoJo" Levesque, Adrian Pasdar, Scottie Pippen, and Swoosie Kurtz.
The Blu-Ray set is a four-disc MOD set. They allow for a play-all mode that lets you pick up where you left off, which is better than the "regular" blu-ray sets for the other WB shows. The only extras are deleted scenes for select episodes. There are no commentary tracks on any episodes or behind-the-scenes material, most likely due to the on-set tension that occurred throughout the season. You could tell that by the end of the season, Crawford and Wayans were being kept away from each other as much as possible while filming, and it seemed like every effort was being made to have them together in as few scenes as possible. Even so, they managed to maintain their on-screen chemistry. You could not tell that they were (reportedly) screaming at each other until "action" was called on set.
It is unfortunate that the two leads hated each other because it was a great show, with the two iconic movie characters cast perfectly. Like the first season, it paid homage to the movie franchise and characters without being a carbon copy. Whether it is good or bad going forward into season 3, it will not be the same without the character of Riggs. Chances are it will not survive after season 3, which is a shame because it was really a show that could have had a good 5-6 season (or more) run in it.
