Worst New Character: Principal Lowry
Principal Lowry is the worst. (Point. Blank. Period.) He barely appeared during Black Lightning Season 2, but he left his negative mark upon the story. Sure, no one can live up to the infamy and positive reputation of Jefferson Pierce; it's a mantle that many will never achieve. However, Principal Lowry had enough salty attitude (and low-key racism) to overstay his welcome. The happiest day will be when his character gets written out.
Storyline That Has Potential: Jen's Growth
Based on the DC comics, Jennifer Pierce's future will involve donning a superhero costume and becoming "Lightning." This reality seems to be the path that the character is taking. Jennifer is making headways with Perenna's counseling; she's adjusting to being a metahuman and she's controlling her abilities. With a bit more practice and confidence, Jennifer could be ready to assume her position. There's plenty of potential for the character to grow and develop beyond her initial character archetype.
Storyline That Fell Flat: The Green Light Pods
After Black Lightning Season 1 built up the Green Light children and the mystery of the pods, the result in the following year came down to ... nothing. Sure, Dr. Jace's betrayal was a shocking twist, but the storyline felt like it was finished abruptly. The metahuman children barely had any impact on Black Lightning's journey before they were extinguished in the faulty experiment. At most, he had a short fight with Wendy Hernandez before she went back into her pod willingly. Let's hope the inclusion of the pods will have a bigger payoff between the characters in the future.
Most Shocking Death: Gambi
Putting the fake death aspect aside, Gambi's murder was the most shocking. Nothing prepared us as viewers to see his car careen off the road and explode in fiery glory. The twist left us with more questions, but it delivered on the emotional impact. And when it became clear that the others were mourning the loss, we had to (even for a short time) accept the fact that he might truly be dead.
The Death We Didn't Need: Syonide
Why did Syonide have to die? The silent assassin had so much presence during her time on Black Lightning Season 1. Her fighting skills were top notch and she was a trusted ally to Tobias. Syonide could've been involved in more plots, but at least we have her epic final fight with Kara as her send-off. She died in battle; that seems so like her.
Villain That Needs To Take A Break: Tobias
Tobias is off his A-game. The powerful mob boss is a shadow of his former self ever since battling against Black Lightning and Thunder personally. He lost his most loyal assassin in battle, he failed to get Khalil under control, he failed to kill Khalil, and he nearly got sentenced to life in prison. Sure, he had a few lucky breaks, but his scorecard earned more failures than successes during the last few chapters. Tobias needs to take a break and leave Freeland to get his act together.
