According to my 2015 YTD
Letterboxd stats I've watched 426 films so far this year... however that figure does include shorts!
I've been a member since April 2012 and have logged the following since then:
2012 - 420 (Apr-Dec only)
2013 - 359
2014 - 350
So the trend has been one of decline in terms of my viewing, except for this year which has seen a spike - I have watched a considerable amount of shorts this year though however.
Also, I was living and working in Shanghai (with occasional business trips to Kunshan, Shenzhen and Hong Kong) from April 2013 - March 2014 so that obviously affected by viewing habits a great deal too.
