From the  trailer,  we can guess it is a childish movie and which can only enjoyed by the children. 

 All the talented actors (taapsee, vijay sethupathi, yogi babu, mathumitha) and immature actors (all others) are staged on one. The bad actor's  acting are actually dissolving the film's story. But sadly, the movie have very weak story base. when we even try to be enjoy the film, the bad & over acting are making us feel disturbed. 

Vijay Sethupathi:

 he is a great actor, but appears from the second half of the film. But the presence of vjs doesn't give any impact on the audience. His acting and performance in this film was very poor as the film is. 

Taapsee Pannu:

Intro song for  Taapsee is not really satisfying and seems like she tried hard to dance. In her group, tapsee  is the one really acting. In the flashback, the English women character is little odd. Having the white skin doesn't really make us believe she is english women.   Others are really over-acting/not really acting. Raadhika Sarathkumar (taapsee's mom), a great actress really wasted in this film. there is no scope for her acting, but overacting all over the film. 

Yogi Babu:

As usual, yogi Babu (comedy artist) trolling the entire crew all over the film. All yogi Babu comedies are not only just to manage the logic mistakes but also makes annoy us after a while. You can't even criticize  the through movie . His predictions are really odd and feels like yogi Babu the patching the defects in this film. But all over the film, mostly are full of patches.

 Jangiri Madhumitha is the only member of her family(in this movie) knows acting. Subbu's acting is very bad even the children can feel a slight disturbence in his presence. 

Jagabathi Babu doesn't really fit with the crew. He does the same corporate villan in this movie too. But with the different costume and aspect.

The movie is a mystery/fantasy film. But it is full of fantasy. the mystery comes at the end caption as there will be a sequel of the film. What is there to make a sequel in this. The OTT released movies are again and again teach us the lesson. the movies in recent days are as bad as the 2nd wave.

Finally, 

the castle has nothing to admire, as the movie.

My Rating:  4/10.
