I have recently watched Thor with my friends in PVR Pacific Mall, Dehradoon. Since the movie timings was from 1: 30 we reached at theatre at sharp 1: 15 but the movie starts at sharp 2'O clock, which was half an hour late.
PVR always delays the movie timings.
Also the sound system was not so much effective, along with that the seats were quite congested. Though the ticket prices were affordable but it could be a more fun if the movie starts at time.
