The good parts:
The episode started well, showing Barry doing some investigative work, with the
general feeling (my take on this) that he could still be a hero, outside the Flash suit/in his daily job.
The DeVoe's seem like a normal loving couple still supporting each other, albeit with high-intelligence, criminal/shady activities/goals and a dying-meta-husband.
The bad parts?
Barry Allen forgot to put on a mask/protective gear while investigating/breaking-and-entering a suspected (meta?) villain's/criminal's/foe's premises yet wears gloves, a hoodie and dark clothing? Highly unlikely.
The team seemed too forced to be dismissive of Barry's suspicions. The circumstances/clues should at least get them to pay more attention to the guy/couple that somehow gives an approximately accurate number of suspects/DeVoes at-the-top-of-the-head, has a fascination with samurai, describes Mina Chaytan as animate (like her powers), complains about harassment by being questioned twice, lives in Central City during the Particle Accelerator Incident and no house-alarms (she did'nt key-in any codes coming in) yet has one camera (based on the fact they only brought one photo) that is somehow angled to show Barry's face in that particular position.
The Worst Parts:
Iris' "we-are-the-Flash" comes back.
