These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
The Firefly Effect: Fans resisted becoming attached: it was on Fox and had "can't last" written all over it. It had however achieved decent ratings and earned a second season. It was cancelled in early May of 2011; YMMV on whether there was enough Executive Meddling to no longer consider it "good".
Fridge Brilliance: Of course Guerrero doesn't care about someone knowing his real name; for all intents and purposes that person is just a cipher, Guerrero is the one that matters. At the same time, using his legal name such that there's a paper trail (which he specifically states when talking to Ilsa) -is- something he cares about to prevent any one from finding his kid. Said kid is also the reason why the seemingly mythical Guerrero has a file at the CIA (remember, before the series, he was like Chance - a hitman that leaves no trace). Since his kid is the only true constant in his life, the company would be able to use that to track him down. Lastly, why use a car bomb to kill the rogue CIA agent? After all, he'd already beaten up the guy and had him at his mercy; it's not like Guerrero is squeamish. Because they smashed up the Eldo.
Fridge Horror: That's cool how everyone fears Guerrero as if he were Death itself. Until you realize that in order for that to happen, Guerrero must really have gone through with ... business ... for his presence to be a legitimate threat.
Fridge Logic: Prior to season two, though the team was ostensibly getting paid by their clients, how exactly they paid for everything remains a mystery given some of their methods.
Heartwarming Moments: In the first season finale, upon returning to the previous Chance's apartment, Carmine the puppy is sitting there, waiting for him. It then becomes Carmines Crowning Moment of Awesome when he leads Jr. to the first of the many hidden weapons around the apartment.
