Entertaining, But barely realistic.

Too much Extreme Fantasy.
Basic knowledge of EMPs CMEs is lacking. Society turning into MadMax within hours was Absurd. Society would take a week or two to even realize and be convinced the lights weren’t coming back on, let alone start hunting down and attacking like animals in 4 hours or even 8 days in.
Big difference between big City Looting immediately in a blackout and rural America at each other’s throats like rabid animals before sundown of the event.
