similarities for this 2 lakorns is the supportive mother in law... both lakorn show that the daughter in law got full support and love from their mother in law... also the bickering moment of main couple where the husband at first find that the wife annoying and is not the wife they want to married as their life partner but end up fall in love with the wife kindness heart... female lead in both lakorn also strong and not easily defeat by their love rival and know how to fight for their rights...

It is very clear that Ryusoulger was trying to bank from what made Kyuryuger profitable. From the Dino motif to the high energy dancing in the change to the exact same color scheme of the core team and sixth.
Other ways they were similar was that both teams were not trusting of each other at the start (The Kyoryugers didn't want to give away their identities at first and Ryusoul Black and Green didn't want to work with Red Blue and Pink), their sixth rangers didn't want to join with the team immediately and they both had villains that had a human inside them which later sided with the team to help.

Both are Super Sentai series
Both are Ninja themed
Both have their ninja rangers start off as students that still have a lot to learn
It had two members show up in it

Both are a sentai team that has their foreign, sentient mechs pick human partners to fight evil. (Engines are from another dimension, Kiramai Stones are from another planet)

Both have their mechas be based on vehicles of some sort. This can range from Cars to Planes to Choppers to Trains.

Both start not having the core team complete and getting the rest very early on in the show. (Go-On Green and Black and Kiramai Red) before getting the sixth ranger/s (Go-On Wings and Kiramai Silver)

Women who sacrifice themselves for love. In "The water magician", aki (Takako Irie) is a famous water juggling performer in a travelling carnival. After falling in love with carriage driver Kinya (Tokihiko Okada), she vows to make sure he always has enough money to make his way through law school. Putting his needs first, Taki makes great sacrifices to ensure there is always money for him in every letter she sends, even if it means that she has to go without. When the money begins to run out, Taki is forced to take desperate measures to help Kinya live his dream.

Similiar theme of much Older man and Younger woman romance that surpasses age and status. Difference is they got married and the series trace their journey past that initial spark of passion. Especially when the male lead hid the fact that he was a rich man.

Maids who fall in love with the heirs of Family's Business who will not have a reciprocated love, care and attention. Women who risk everything for love.

Movies about Independent women. In "Flame of my Love", a woman struggles for equality in Japan in the 1880s. Eiko Hirayama leaves Okayama for Tokyo, where she helps the fledgling Liberal Party and falls in love with its leader Kentaro Omoi

Both movies are show the courtroom and trial of women accused of killing a family member. In "Women's victory" Kinuyo Tanaka is a lawyer defending a woman who killed her baby in a moment of madness and despair. The prosecutor says that laws are laws and must be interpreted as such; Tanaka argues that laws have to be contextualized in the broader scope of society and she places blame for the murder on the failure of the Japanese government to look after the sick and injured (the accused's husband worked in a munitions factory during the war, was injured, and the family was driven into bankruptcy because he didn't get proper compensation).

Both are remakes from The Little Nonya, of which Precious is more of the family setting in China and TLN (2020) is more closer to the original. Same actress Jeanette Aw acted as the main lead in Precious and the original The Little Nonya. And also Actor Dai Xiang Yu acted in all 3 dramas.

Both are mysterious and clue-finding variety shows. While Crime Scene is more complicated, thrilling, and wholesome, Village Survival was more on the funny side and laughs.

Both have main characters with ambiguous morals/motivations/psyche. Both (so far) manage to keep their anti-heroes likeable while not toning down their darkness. Extracurricular has a much more intense and fast-paced thriller plot, while IONTBO (so far) has a more leisurely pace.

I watched PYHOMS first and it became one of my favorite dramas. I even rewatched it (which is rare of me.) I can't tell you happy when I discovered Love Equations. While the stories are not the same, the characters truly reflect each other. The FLs are strong, quite independent, and cute. But they are not portrayed as perfect and often times come off clumsy. They both make mistakes and own up to them as well. The MLs are calculated, ingenius, but also loyal to the FLs. While the MLs know nothing outside of the STEM field, both find themselves clumsily stumbling into love with the FLs.

Honestly both are absolutely perfect and should be a go-to when you need a refreshing drama to get you out of a slump, or a drama to boost you mood, or at really any point in life.

Both movies share VERY similar plot lines. Both involve two boyhood friends. One grows up to become a cop, the other seems to have had an unknown fate. The cop investigates a series of serial killings throughout the movie and makes a startling discovery about the fate of his boyhood friend.

The same style of series however different storylines. I got a similar feeling when watching certain scenes this is most likely because both movies have a serious person and a person who likes to mess around all the time not to mention the brotherly love.
