And by younger, I mean like. Child young. CM:SB, despite being a spin off show, is essentially copying Criminal Minds, just with more weirdness, since the "nontraditional" nature of the fiction Red Cell teams means there's nothing off the table. The only protagonists I care to remember, let alone care about, are Agents Cooper and Mick, and maybe Prophet, who has a one-episode story arc and then nothing. Sam "Coop" Cooper (Forest Whitaker) is a deeply spiritual, and even somewhat mysterious man wit a strong faith and even stronger devotion to his job, using powerful empathetic methods to tap into his profiling skills. Mick Rawson (Matt Ryan) is an ex-Special Ops sniper with a badass accent and even more badass skills, both with his rifle and his profiling (though the latter isn't showed off at all). Johnathan "Prophet" Simms (Michael Kelly) is an Ex-FBI-turned-FBI- again agent who has an admittedly okay arc in the season premiere, detailing his prior mistake and newfound redemption with Cooper, but then kinda just falls short.
Overall, if you like Criminal Minds for the psychology, you'll probably at least be okay with Suspect Behavior's existence. If you're in it for the rich characters, you'll stick around for Cooper probably, or at the very least Kirsten Vagnesse, who reprises her role as Penelope Garcia. If you're in it for the storytelling, you'll probably wanna stick to the original series.
