I decided to watch this anime because of my friend. He was praising how good and creative the death games are. What I didn't know was that he meant the manga... not the anime...
Spoilers~ be warned
PROBLEMS
Unintentionally funny moments
Let's look at the genres: drama, mystery, psychological, thriller.
While watching the anime there was a traitor among the main cast, someone has willingly put everyone into a potentially life or death game and when the traitor was revealed this is the face I saw:

I couldn't help but wheeze so hard at this.
He be looking like this guy:

So considering this is a PSYCHOLOGICAL THRILLER I expect at least some clever ways of tricking the viewer or the characters. So 3rd game begins and the big strategy, to trick the other team is to make a girl stand in her underwear... are they for real?...LMAO I can't even handle how stupidly funny that was.
Observers

(Why is Touka from Tokyo Ghoul here)
There is nothing more annoying than these two explaining everything to me. It's like im treated as a baby and being fed while being said "Here comes the choo choo train". Isn't this suppost to be a psychological thriller? What's the point in babying the viewer eatch step.

OMG WHY DID THEY ADD A 3RD ONE
(all I remember is her boobs honestly)
Plot
First half:
OH NO I'M PSYCHOLOGICLY SCARED AT HOW FUNNY THIS IS. At least the first half was mostly that, before the third game. The plot twists at the start felt so unimpactful since, It's so edgy and the cliches were killing me. Another issue was the host or I guess the mascot Manabu, he didn't help any more too, because how am I supposed to be thrilled with this goofball around.
Second half:
When we got into the third game with two teams K vs C it got more interesting and at times I enjoyed myself. What was the biggest improvement is Kei vs Yuuichi. Another thing I liked was Maria entering the game too.
Overall
The plot treats the viewer not only like a baby but an idiot too, so many plot holes, edgy plotwist after another plotwist and after another one makes the watcher take the story less seriously. Oh, what's going to happen next? Someone's dad dies again? No way right? But thanks for it having the edginess level to such high degrees it's actually entertaining in a funny way. As a psychological thriller it falls into below average story writting.
CHARACTERS
Tenji Mikasa
This creepy weirdo was the funniest thing in this whole dumb show. His personality and motives changed like 5 times from being shown as the most intelligent, rational guy to a sick freak who is too into his ex (god what was that scene with him naked together with her), then the guy claims to be gay then pulls out the sike card again and he is not gay and says "oh yeah the ex I was obssesed with is all a lie I hate her". I have never been more confused about a character like this. But he definitely got the worst luck and suffered the most trough the whole anime.
Yuuichi Katagiri

Sicko number two (like seriously is he some sociopath or psychopath). Alright, this guy is one of the more interesting protagonists I've seen in anime. This dude's personality did a 180 and this, not going to lie interested me. The good acting and multiple bamboozles he does to everyone are fun. He brings the thrill aspect into this garbage anime plot. He is so unpredictable, one moment he acts one way the other contradicts everything he says. His motives to me are confusing and unknown, I can never see what random weird thing he will pull next. The reveal of him being a murderer at the start didn't surprise me at all though, thanks to the edginess from the beginning and the observers constantly saying something is weird about him. So if that had to surprise me, it didn't.
Kei Shinomiya

The true leader of Group K turns out to be this baby face. A challanger for Yuuichi? He is as sharp as him so at least we got more than one entertaining character. He definitely has potential, too bad we got to see him for such a short while. (Why did he get spanked on the butt)Good qualities
Opening - they did a great job at animating and the song itself so catchy.
Trashy gold comedy - the fun comes from not having to use my brain and enjoying how stupid the plot is. This trashy show.... it's so bad it's funny.
Conclusion
After watching this anime I felt brain dead but at least I had a lot of laugher of how god awful this plot was.
