Was 2015 the year of Bs? Bollywood had a splendid year with Baahubali, Bajrangi Bhaijaan, Baby and Bajirao Mastani

What classifies as a good film? Is it one that rakes in the numbers at the box office? Or is it one that enjoyed positive reviews? Better yet, what about a film that manages to do both?

When it comes to Bollywood, movies featuring the superstars have always opened to almost unbelievable collections. However, the initial hype wears off after three days. The film then survives solely on its word of mouth, and audience reaction. Let's look at the recent Khan blockbusters - Happy New Year and Prem Ratan Dhan Payo. While both films managed to find a place in the much hyped Rs 200 crore club, the films failed to trend well at the box office after the huge opening weekend - owing to largely negative reviews.

As 2015 comes to a close, let's take a look at the Bollywood films that have worked purely on the basis of word of mouth. How can you tell that a film has enjoyed great word of mouth? When the lifetime collections of a film are at least three times the collections of the opening weekend, that's when you know that audiences have genuinely liked the film.

Going by that, let's calculate the Trending meter like so:

Trending Meter = Life Time Collection / Opening Weekend

Dum Laga Ke Haisha:

Tanu Weds Manu Returns:

One of the biggest openers of 2015, this sequel to the much-acclaimed Tanu Weds Manu collected Rs 38 crore at the box office on its opening weekend. The film's solid performances, catchy music and a taut script garnered some rave reviews. The film ended its box office run with collections almost touching Rs 150 crore.

Trending Meter: 3.94

Baahubali:

There's nothing small about this film. From its budget, to its box office collections - Baahubali truly is India's biggest film to date. Not only did the film shatter all records at the regional box office but also managed to set new benchmarks for regional dubbed films. After a moderate opening weekend of 22 crore in Hindi, the film ended its run at the box office by raking in Rs 120 crores - becoming the first Hindi dubbed film to rake in over Rs 100 crore.

Trending Meter: 5.46

Bajrangi Bhaijaan:

Trending Meter: 2.81

Talvar:

Despite a clash with Akshay Kumar's commercial entertainer, Singh Is Bliing, Talvar held its ground well by performing well at the ticket window. After a below average start of a Rs 9 crore opening weekend, the film - based on the Arushi Talwar murder- held well for a couple of weeks before ending its box office run with Rs 30 crore.

Trending Meter: 3.34

Baby:

A film which deserves a special mention in the list is Akshay Kumar's Baby. Though the film failed to meet the criteria by a small margin, it won acclaim from audiences and critics alike. After its weekend collections of Rs 36 crore, it went on to collect Rs 96 crore in its lifetime run.

Bajirao Mastani:

The Sanjay Leela Bhansali magnum opus, Bajirao Mastani, which clashed with Shah Rukh Khan's Dilwale on 18 December, managed to shatter all expectations and rise above the Rohit Shetty entertainer. After an opening weekend of Rs 45 crore, the Ranveer Singh-Deepika Padukone-Priyanka Chopra starrer is looking to end its lifetime run at collections close to Rs 170-175 crore - which would be about 35-40 crore more than Dilwale.
