The film's main flaw is it weakly carries the plot and instead of deepening and exploring the themes, it diverts into another. I'm sure that the intention was to make Lost a thrilling experience but it ends up being a dull affair with its slow plot and almost non-existent suspense.
Yami Gautam gives a disappointing performance with her patchy dialogue delivery and unconvincing portrayal. Despite having a great character, her one-note performance falls flat and makes the story look untrustworthy.
On the whole, Lost is a tedious watch with a lack of deftness in writing, direction and acting. There are few moments of brilliance but overall it fails to create an enjoyable experience.
