IMDb(The Internet Movie Database)is world’s most popular and authentic source for movie, TV and celebrity information, reviews and content. In simple words IMDb.com is the best site for fetching reviews on TV serials and movies. The reviews and ratings provided by this site are very acceptable in genral, as movies and TV series are rated and reviewed by common people like us. I have been using this site for years now it helps me to decide whether a movie is worth wathing or not.
Its very easy to find review of a particular movie or TV series you can simply search it in IMDb you will get the results instantatly. Catagories(genres, years, actors, etc) provided in the site makes easier to search a movie and navigate through the sites.
CONS: Be careful while making impression about a movie based on rating provided in IMDb. First of all check how many people have voted for it. If one person have rated 10 points to a particular movie and he is the only person have voted then that movie will get 10 star rating but that doesn’t makes it a good movie.
But if huge number of people have rated it 7 stars on an average then it must be a decent movie.
