Looking at television schedules available on the web, "Shockwave" is the last Flashpoint episode CBS will air during this summer, and, given Nina Tassler's recent comments, potentially the final episode of the show the network will air. I don't believe this signals the end of the show since it was renewed for a fifth season and is still popular in Canada, but nothing is certain.
In any case, "Shockwave" is a strong episode to end on. It's a tense episode, filled with the emotional moments we've come to expect. The format is a bit different than usual, with the team mostly stationary throughout the episode. Spike, Sam, and Raff are stuck in a building with a massive bomb which will detonate. This cuts out some of the less potent scenes like driving around places, allowing for more focus on the characters right at the center of the action.
There's a lot going on--Spike's father having a clout and possibly dying, Sam having a concussion, a woman trapped under rubble, and mostly importantly, the bomber hiding with them in plain sight--and it's all heavy stuff. But everyone pulls out in the end and after a whirlwind ride, the audience can finally breathe a sigh of relief.
Score: 9.0/10
