Aranmanai4 is the latest installment in Sundar C's popular Tamil horror comedy series. The film continues the tradition of combining humor with super natural  elements but with some special twists that set it apart from its predecessors. The story revolves around Saravanan(Sundar c), a lawyer who learns of the mysterious deaths of his sister Selvi(Tamannah Bhatia) and her husband. The tragedy leads him to a village where he finds out that their deaths are not as simple as he thought. As Saravanan digs deeper, he encounters  a series  of supernatural occurrences  linked to an evil spirit named  Baak, which forms the core of the film's thrilling story.

One of the strengths of Aranmanai4  is its ability to maintain tension and mystery. Unlike previous  parts of the series, the evil forces do not wage a personal feud against the protagonist's family. This  broader narrative framework allows the film to weave together seemingly unrelated event, keeping the audience guessing as to their connections and eventual revelations.

The acting is notable, particularly Tamannah Bhatia's portrayal of Selvi, which gives the film emotional depth. Sundar C's character takes a backseat for most of the running time, allowing the supporting cast , including  Raashii Khanna, to shine.

The comedy, a hallmark of the series is the weak at the beginning but improves as the film progresses, with the pre-climax sequence being particularly humorous.

Visually, the film employs the  effective, albeit  somewhat banal, visual affects to enhance the supernatural elements, bringing them to life.

Background music by Hip Hop Adhi complements the tone of the film, enhancing both  the horror and comedy moments. However , some critics believe the film  would  have benefited from a more detailed exploration of the supernatural lore and the power of the spirits involved. Visually , Aranmanai4 brings the VFX elements to life with effective visual elements, although some critics feel the film could have covered the supernatural story.

Overall, Aranmanai4 manages to entertain with its combination of horror, comedy and emotional  story telling. Though the film follows a familiar pattern, it introduces enough new elements to keep fans of the series hooked. The ending hints at a possible fifth installment, ensuring that the Aranmanai  series  will continue to captivate its audiences.

Despite some criticism,  Aranmanai 4 manages to deliver an entertaining mix of horror , comedy and emotional storytelling. The film's ending hints at a possible fifth installment, suggesting that the series still has a story to tell and continues to captivate audiences.
