The movie "They Call Him OG," starring Pawan Kalyan, received mixed to moderately positive reviews. It is largely seen as a stylish gangster drama catering mainly to Pawan Kalyan fans. Critics appreciated Pawan Kalyan's energetic and controlled performance, especially in action sequences and punch dialogues, calling it his best in a long time. The film features strong technical values, a terrific background score by Thaman, and stylish narration. However, the storyline and emotional depth were criticized as weak, with particular disappointment in the second half, which was seen as predictable and lacking compelling drama. The film is described as more about fan service and style than substance or a strong emotional core. Key points:

• Pawan Kalyan's retro look and performance were highlights.
• The first half and action sequences were engaging.
• The second half was weaker with a stretched story and less impactful drama.
• Sujeeth's direction and Thaman's music were praised.
• The film works well for fans but may not appeal broadly due to its familiar plot and lack of depth.

Overall, "OG" is recommended mostly for fans of Pawan Kalyan as a mass entertainer with style rather than a deeply compelling gangster film.
