Before getting mad at this review, lemme just say this is one's opinion just like anyone else's. If you liked it, that's great, my opinion shouldn't be an offence to yours. To reiterate, this is an opinion.
This BL was definitely up there in terms of hype for me. I was looking forward to watching such an action-packed drama, and while it delivered for some, a lot of it fell back for me.

What makes it good?
I enjoyed the use of colours and lighting for some of the scenes to give it more of a mafia aesthetic. The scenery for some episodes worked splendidly and there's so much more than just one simple location. It added a lot more to the overall dark raunchiness of this show. The acting is great overall, Bible and Apo being among my favourite actors of the show. Some of these actors are rookies which amazes me how they took on such a complex role and nailed it super well. Born actors is an understatement. The psychological aspects of the show are also intriguing to me, because of its complex nature in KinnPorsche. I don't know if it was intentional in some parts, but it made the characters a little more lifelike.

What makes it bad?
The subplots are one of the biggest problems I struggled with while watching this. I became so lost due to the nature of the pacing. "Where was the plot going?" was something constantly swirling in my head, because it felt like it was going one way before doing something completely different. The editing was at times cheesy CGI effects that didn't make sense, especially towards the end. Some of the music didn't fit the scenes or takes you out of focus. This next point might be polarized but the whole "morally grey" direction they went with the characters felt like a quick label to add as justification. While yes the rating, the whole mafia notion of the show makes you expect to see the morally grey side, I couldn't find any of that with the relationships, because they started off bad and didn't improve as the episodes went on. It felt more black and white, as in "here is character, this is their backstory, now their actions are justifiable". Yes, this is a fictional show, but some parts of it I can understand will make people very uncomfortable due to the execution of such scenes. Also, yeah this is a BL but the lack of women in this show really felt offside. They were mostly put in the plot as a "here's a woman" and then disappeared like a Thanos snap (the same feeling for a certain pairing was treated as a "side support character"). Give us more badass women in mafia shows, dammit!

I was expecting to jump into this mafia drama and be amazed, stunned, whatever else relates to shock in the dictionary, but a lot of it didn't jump out at me. There were some very interesting parts, don't get me wrong, but the entire plot was messy and didn't make much sense. This has cool action, great acting and a neat psychological dive, but that's really all I found were the best parts of KinnPorsche.
