Let's start with these that stands out.

Cinematography was really great,so the Direction.Everything was very pleasant to the eye.They did a really nice job here.
Music was excellent all the way,every scene had its appropriate music theme.And lets be honest,"Dancing with the devil" is a Killer!Hands off!

Now let's talk about all those things weren't that great and practically prevented me from giving a higher score.

This had all the potentials to be a Super Hit,but unfortunately failed.
No is not the best story out there,nothing is remarkable about it.Nothing new,steps on the old good premises of any Bl.
Enemies to Lovers the most common trope,we just love to hate.Yes to me is always an intriguing trope and i do not mind at all when writers use it so much.
By default is more spicy and gives more room for development,if it is used right.
Here was just too plain,too predictable and occasionally boring.
They decided to start this story the most toxic way they could.

Allow me to open a parenthesis here:
Let me clear, i dont mind toxic relationships,iam not shocked,and definitely iam not prude to curse this kind of stories.Iam old enough with real life experiences and iam not hiding behind my finger for the sake of being nice and acceptable.I don't care.Toxicity exists in Real Life,too.I close the parenthesis here.

So back to the story as i said had great potentials if they had spend more time and effort to develop the 2 main characters in more depth.Always is a plus to any story when we can get deeper to each character.Also it could be more episodes if they had done this.

I would prefer the story was more mature,as the outline could give space for this.Instead, almost every reaction to any action was just childish.Considering the main leads are not school boys( Uni students who also runs family bussiness are adults,right?)they should had dealt with all the occurring problems with more responsibility.
Actually the story was a bit of everything,a mix and match.Wanted to be spicy and..kinky(!!!)but ended up soft and awkward.Lol!There is not a clear path,like in the midway the script was "censored"somehow and the writer had to change the main concept.Or he was confused and not so sure if this was a soft or a hardcore story!At least this was my notion all the way from first to the last episode.

And now i will talk about the main problems this series has.
The Acting is one of them.
If iam not mistaken the main leads are both rookies and Big Dragon was their first project.
It is always great to give opportunities to new actors and having the main roles i guess is big enough but also can be too stressful.But this is the only way they could gain experience,too.
So iam not blaming those 2 kids as they did their best.But yet i suppose they both have a big road ahead,to improve their acting skills and iam wishing them the best.
Stiff,awkward,unnatural,embarrassing,are the words i can use to describe the acting here.
(and if you think is me being a bitch here,i assure you iam not,as i was highly impressed by Bible's acting in KinnPorsche and i praised him a lot even if he was a rookie too)

The second issue was chemistry among the Mls.Or better say the lack of it.Zero,none,nothing.They didnt convince me not for a second that they were inlove,no passion even in the sex scenes.Clearly both were too embarrassed not only to kiss each other but to just touch each other's hand!Yeah for a BL that was a bummer.

So my final words about Big Dragon.
It could be so much more.It could be FIRE and one of the most hot Bls of 2022.
A more bold script,a little more depth in characters and maybe different actors as main leads could have give the right push to be a Hit.
Still it was enjoyable and got a 7,5 from me,passing the average and be in the good "league"
