Drona is a Superhero Fantasy film. The film starts out pretty well but lacks depth to hold the attention of the audience. The story line is thin and there's not much one can do with such a story line. The movie could have been a lot better, though some of the sequences have been shot very well. The actors have performed well and the best part of the movie is it's special effects. The relationships between the different characters hasn't been brought out well enough due to which the film fails to say what it went out to say.
All in all, watch the movie if you like hollywood fantasy tails and special effects. Otherwise it's your wish.
