Primarily, I believe Dhanush's downfall is purely because he is insanely obstinate and not at all flexible. Despite his great acting talent, he finds it difficult to switch and break the barrier. Mahesh Babu also suffers from the same syndrome. But he is a much hard worker and constantly tries to break his limitations. He is ready to experiment with himself. Breaking his chocolate hero look. Dhanush, unfortunately, is in a cell that he doesn't want to break.
I do a bit of character study as a hobby. Here I don’t have other means available for a proper character study apart from referring to his Sun Signs. So I checked the sun signs of both Dhanush and Mahesh Babu. Mahesh Babu (Born August 9) and Dhanush (Born July 28) are both Leos. The Fire sign. Indian astrology is moon-based. So typically, you will have two zodiac signs. And there will be a tug-of-war in your character because of the impact of the two zodiac signs.
However, if your birth time is daytime, the sun sign could have a stronger effect on your character. If it is night, then your Indian zodiac sign will have a stronger effect. Further, the position of the moon, like the New Moon Day or No Moon Day, or Full Moon Day, could make a lot of impact. Anyway, I am purely going by Sun Shins, no astrological prediction, just character study.
Leo characteristics: Element: Fire, Ruling Body: The Sun, Symbol: The Lion. Typically, Leos are very strong people by character and are born leaders. However, there are many cons also. Dhanush's former wife, Aishwarya Rajinikanth, was born on January 1, 1982. Her Sun sign is Capricorn, the mountain goat. The mountain goats are very tough. They are extremely comfortable at any social height. But Leo and Capricorn are not compatible Sun Signs because they are the Lion and the Goat.
Their relationship couldn’t have gone very smoothly. Although mountain goats are not easy prey for the Lion. The mountain goat can scale great heights that the lion mostly wouldn’t be able to catch. So their marriage survived 18 years. Another reason for the survival of this marriage so long is that the Leos are fiercely loyal when they are committed to a partner; they are intensely devoted and protective. But overall, it was an incompatible relationship, sun-sign-wise. So the relationship survived long despite the tug-of-war. I suppose Dhanush’s birth time is daytime. So his Leo character is strong.
A strong Leo character would find it difficult to surrender to the dictates of the director and producer, particularly if they are not from compatible sun signs. No surprise, Dhanush produces his own movies. I spoke about Mahesh Babu as well. he also finds it difficult to break the barriers.
Ram Charan and Allu Arjun are both Aries in their Sun Sign. The Aries Sun Sign is marked by a bold, ambitious, and natural pioneering spirit. Both are ruled by Mars and belong to the Fire element. The Arians approach life with relentless energy, unwavering confidence, and a passion for new beginnings. See the flexibility of the roles played by Ram Charan and Allu Arjun. Both feel absolutely normal for any kind of role. They transform very well into all types of roles.
Now, compare Dhanush and Mahesh Babu in that matrix. I can bring many other actors into comparison to expand my explanation. But not required. When it comes to acting skills, Dhanush is undoubtedly the best. But he is confined by his Leo strength. Mahesh Babu is a little more open in comparison to Dhanush. A lot depends on childhood and upbringing. Dhanush had a childhood marked by financial hardship and strict family discipline, followed by a youth dominated by a forced entry into cinema. Mahesh Babu, on the other hand, had a much more relaxed childhood since he comes from an affluent family.
If you observe very minutely, you will find a touch of inherent anger in Dhanush because he had to fight a lot. He finds himself very comfortable, and his natural flair connects him well with common people. Theatrics doesn't work much with him. he has that hold-back attitude which you wouldn’t see in Allu Arjun and Ram Charan. I am quite happy with Mahesh Babu. He constantly keeps challenging himself with roles that are actually not his forte, based on his characteristic strength. His natural flair comes automatically when he plays an affluent, sophisticated role.
I feel Dhanush needs to have a psychometric analysis and seek the help of a top grooming coach to come out of his limitations. But possibly his intellectual pride will get in the way. However, he has no other way but to have consultants to work with for transformation and film, as well as script selection, where he can still give his best while holding his characteristics.
Two Hollywood actors come to my mind who are Leos. Robert De Niro. Robert Anthony De Niro is an American actor who was also a producer, like Dhanush. Nero is widely regarded as one of the greatest and most influential actors of his generation. What an actor Nero is. Nero won the Academy Award for Best Supporting Actor for his unforgettable role as Vito Corleone in the crime drama The Godfather Part II (1974). He was the first male to win for an Italian-language performance. Nero is legendary when it comes to acting. Dhanush is not in that league. But with the right kind of director, he can definitely have a shot.
Jennifer Lopez is another Leo actress who is known for her dominance on the screen. As a Leo, Dhanush has His pride that can make it difficult for him to admit when he is wrong or apologise after a disagreement. Typically, Leos find it difficult to adopt a correction process because they have to give up their ego and pride. They are vulnerable there. The characteristic could be the same for people born under the Indian zodiac sign Leo.
