Ramanunni(dileep) a left wing member shifts to right wing due to having a fallout with its leader ambadi mohanan(vijayaraghavan). Ramanunni contests for election but soon is charged for murder of mohanan. Rest of the film is how ramanunni proves his innocence and wins the election.
After a long time we get to see dileep in a no-nonsense character in ramaleela. He's smart and intense. Vijayaraghavan is seen in a negative role after a long time. Siddique is great as usual. First half is very engaging with lots of mass moments from dileep. Background score of gopi sundar elevates the movie sometimes.
But on the flipside, second half turns mediocre when it turns into an investigation film where ramanunni and chacko are staying in a big boss kind of ambience. Shahjohn's comedy turns annoying in second half. Also there are some loopholes in script. Climax is like a fan service. Ramaleela has a engaging first half and a mediocre second half.
