LIKES:
Cinematography (scene locations), colour pallet and fighting choreography was all very well done. Production was good (they thankfully knew how to use a film stabilizer.
Editing and directing for the most part was good too.
Most of the special effects (gore) was pretty good.
The violence and gore, with some creative moments, were good.
Casting was excellent as all the actors & actresses were well selected for their roles.
Just enough romance to satisfy any viewer.
Enjoyed Vincenzo being both the “good gangster” and the cold blooded mafioso.
I did like the creativity in the deaths of certain characters.
Ending was concluded well enough for all the main and supporting characters.
Decent OST, but sometimes the music was too loud and it made it hard to hear the actors/actresses speaking.

DISLIKES:
Too much comedy and some of it was just plain stupid.
The main evil boss was more sociopath, than psychopath, writers didn’t do enough research. The bad/evil characters were so predictable and typical.
Not really a crime drama or law drama, strange kind of mash up with heavy cheesy comedy.
The characters trying to pronounce Vincenzo’s name, wasn’t funny and got annoying fast.
Too many supporting characters or side characters, which made the plot get bogged down.
A lot of filler scenes that were pushed on us as being law, court and crime related, to show how bad or good the characters could be. It just made the show a little too long.
It’s more about being a vigilante than a mafia gangster and it constantly flip flops on who’s the lesser evil.

OVERALL:
Birds of a feather flock together was a strong theme throughout, both literally and figuratively. Better than some of the kdramas of 2021, but still lacking and a bit over hyped. I would recommend it and I have watched it again (but did fast forward over a many parts). Not what I expected, but didn’t disappoint me like it did for others.
