It's good, but it could've been great. 'Jagga Jasoos' has a lot of positives, but there's one big negative that affects everything else - the run time. There is simply no reason for this to be 155 minutes long, there's so much unnecessary faffing about. There's a fantastic spine to the film, but it's just flooded by lameness. Ranbir Kapoor is entertaining in the lead, he very much commits to the role of Jagga - he's amusing but does have a few moments of heart also. Katrina Kaif (Shruti) and Saswata Chatterjee (Bagchi) support Kapoor extremely well. A few of the others, like Saurabh Shukla, are decent too. The music is pretty good, the core premise has potential and the cinematography et al. is solid. I'm not completely sold on how the story is told, I mostly liked it but the back and forth nature does annoy in a few parts. In short, it's worth a watch - but snappier pacing would've raised this film up higher in my ratings.
