There's a ton of reviews on this one, as a non-Indian who gets to watch a decent amount of Bollywood I agree with the mainstream view here that "Fan" is a decent thriller with a return of SRK to old form after a few lackluster movies.

Quite a few reviews here claim that this is a remake of 1996's "The Fan" starring Robert De Niro as the obsessed fan of a baseball star played by Wesley Snipes. This is simply not true. There is no hint of identity theft in that film (but family theft, yes). This is the crucial element here so the comparison is completely off the mark.

It is, however, justified to say that this kind of story has been done many, many times, as in the rather gory "Fan" of 1981 starring Lauren Bacall and Michael Biehn or the similar German "Trance" (1982). I found myself waiting in vain for any surprises, even though SRK's performance makes it worth to watch.

It is also true, as some reviewers have pointed out, that the settings make some plot elements unrealistic. For instance, you cannot wear a hood in London's attractions, let alone a gun. The entire city is under CCTV surveillance so jogging with a hood will alarm police. To use Blenheim Palace, a well-known historical landmark and birthplace of Winston Churchill, as a private residence of an Indian mogul located in Dubrovnik, makes this movie a bit ridiculous to Europeans and may have harmed its marketability. It's fine to set a chase scene in Dubrovnik, a very beautiful city, but it stretches just about any credibility when you have SRK start to give chase outside of a huge English palace and then cut straight to the rooftops of a medieval Mediterranean port. That's kinda like have him step out of the Taj Mahal and run down the streets of Shimla.

So it's not a disappointing film, just the script is rather lazy and one would have expected a surprise turn of events, like Aryan realizing that his crazed fan is actually his schizoid other self. SRK could have pulled that off. There's a lot of build-up petering out to nowhere.
