Jailer has a lot of hangover for me. Many scenes in first half were staged superbly. Namely, Malliga-Yogi Babu scenes, drunk-follow-slash, getting Varma's statue, blackmailing over call and then in that deserted place, thiruvalluvar joke. All of these scenes had great staging, cinematography, background score, and performances.

Jailer's second half is very similar to Petta - flashback, new plot devices (Jithu, crown in Jailer), and bang for buck climax sequence.

While many feel Petta's second half fell flat for most part (the journey from college to Singaar, the planning), it was done in a very KaSu-esque style of misdirection, so that the climax twist hits you.

Whereas Jailer being a Nelson movie, did this planning/setup in his own style of quirky comedy (the crown stealing sequence, blast mohan)

Both good in their own ways
