What happens

Stupid Genius, in Vietnamese Thiên Tài Hạng Bét, is a six-episode boys' love web series from RL Studio, released on YouTube between 9 June and 14 July 2023 with English subtitles on every episode. Nguyen Thi Thu Ha directed. Episodes run fifteen to twenty-five minutes, with the finale stretching to twenty-seven.

Khoa, played by Pham The Bang, is failing his subjects. Vinh, played by Nguyen Tien Hai, is assigned to tutor him. Khoa is also the class monitor, even though he sits at the bottom of the class, while Vinh is its top performer. Nguyen Thai Khang plays Hoang, Nguyen Quoc Nam plays Kha, Cindy Diem Mii plays Thao and Truong Minh Thao appears as Mr. Tuan.

The setup keeps the story small. A student who is behind and a classmate who is ahead are put at the same table, and the lessons are the reason they keep meeting. Khoa and Vinh are the two characters the story keeps in view, while Hoang, Kha, Thao and Mr. Tuan fill out the people around them.

RL Studio released the series with a trailer, an original soundtrack video, a behind-the-scenes clip and a cast reaction video, and posted the whole run as one upload of about an hour and forty minutes under the alternative English name Great Genius.

6.6/10

The title already tells you the joke: a genius at the bottom of the class. Stupid Genius, or Thiên Tài Hạng Bét in Vietnamese, is a tiny RL Studio series about a student who keeps failing his subjects and the classmate stuck with the job of getting him through. Six short episodes, lots of study-table comedy, done before your snacks run out.

Homework, Under Protest

Khoa (Pham The Bang) is failing his subjects. Vinh (Nguyen Tien Hai), who is well ahead, gets assigned to tutor him. So now one student who is behind and one who is ahead share a table, and the lessons become the reason they keep crossing paths. Around them, Nguyen Thai Khang plays Hoang, Nguyen Quoc Nam plays Kha, Cindy Diem Mii plays Thao and Truong Minh Thao turns up as Mr. Tuan. If you like light school comedies about study sessions, mismatched classmates and coming-of-age wobbles, this is an easy, cheerful pick.

RL Studio's Favourite Recipe

Fans of the studio will spot a pattern. In The Star Always Follows You, a student who failed his exams gets a teacher in a village. Here a student failing his subjects gets a tutor at school. Same simple frame, two people, a lesson and a recurring hour, told at a different size: nine episodes there, six here. Director Nguyen Thi Thu Ha returns too, and so do some familiar faces. Pham The Bang, who played Vi in that series, leads this time as Khoa, and Nguyen Thai Khang moves from Quan to Hoang. Truong Minh Thao, known as the lead of O2 Production's Mr. Cinderella, brings a face from another studio into the mix.

Short, Subtitled, Sorted

Six episodes of 15 to 25 minutes, with a 27-minute finale, went out weekly on Fridays on RL Studio's YouTube channel from 9 June to 14 July 2023. Every episode carries English subtitles, which makes it a very friendly first stop for international viewers. The studio also posted the whole run as one upload of about an hour and forty minutes under the alternative English name Great Genius, so do not be confused if you see both titles. Extras include a trailer, an original soundtrack video, a behind-the-scenes clip and a cast reaction video.

Sample Before You Commit

It is an original story with no book behind it, so nobody can spoil it for you. My tip: if you have never tried Vietnamese web series before, this is a painless taster. Put on the Great Genius compilation, give it one evening, and then decide whether to move on to the studio's longer village story.

Final Score: 6.6/10

Themes and Messages

Stupid Genius is made for the short form from top to bottom, and RL Studio kept the whole release on its own YouTube channel, extras and all. Handy for you: everything sits in one place.

Tutoring is the hook. One student is failing his subjects and another is assigned to teach him, so the story stays in a small, contained world: a table, a set of lessons and the people around them. The comedy comes from that mismatch, the one who is behind next to the one who is ahead, and the coming-of-age part comes from what each learns about the other along the way.

At heart it is about study pressure, patience and the odd friendships that grow when two very different classmates are made to sit together. Uff, we have all had that one desk partner.
