I would never have thought at the beginning that I would give DFF such a high rating. Because the first 4 episodes were pure guilty pleasure for me. This mixture of 90s slasher parody seemed like pure trash to me, but at least it was entertaining.

But then came episode five and the tone changed so radically that you thought they had replaced the director. From pseudo-horror in an abandoned house, it became a sad psycho drama about an outsider whose bullies took it too far and he had to suffer terribly as a result.
It's not always nice to watch and often gets under your skin, but it's always coherent and comprehensible.
Overall, DFF can be seen as a revenge thriller and in this respect it is completely convincing. Even if the start was very bumpy and even later, when the abandoned house takes center stage again, the whole scene seems a bit chaotic.

In terms of acting, you have to differentiate a lot here, as there are mostly newcomers at work, which you really notice at the beginning and the whole thing degenerates into total overacting. But fortunately there are exceptions, Barcode, whose performance as Non is really so believable, hovers over everything. A little too weird, a little too weak, he is simply the perfect victim and his ordeal simply gets under your skin.
But other actors also have their moments Ta as the main protagonist, who is also rather morally gray on the road, and JJay as the emotionally cold young killer are quite convincing.
The rest of the cast are mostly convincing in the quiet moments, while unfortunately they don't always get the horror moments across well. Jet in particular seemed rather annoying to me throughout the series, which wasn't necessarily just due to the role and he should urgently take a few more acting lessons.

Conclusion: if you get through the first four episodes, you'll discover a dark and unsparing gem. The fact that DFF is so uncompromising and shows the emotional horror so well is its great strength and sets the series apart from others. Even if the acting is not always top-notch and the final episode is quite controversial, I would recommend DFF to anyone who wants to watch something other than the typical BL Rom Com
