I have to disagree with earlier posters assertions that the sequels /reboots /high budget films of this year are nothing new.
I respect the other posters going back to the dawn of film and modern plays for their arguments, but I don't really think those comparisons are relevant. There is virtually nothing similar between entertainment consumption then and now, nor could you really compare the budgets of films from then to now - even adjusted for inflation, the biggest budget movie in 1927 would have only cost $26 Mil in 2016.
I think in discussions like this you have to stay modern - and in that case, this is a year with more sequel and reboots than ever before, and a year with more blockbuster budgets than ever before. The first summer blockbuster came out in MARCH this year with BvS. Den of Geek had a write up about it, as did several other sites, but unfortunately I don't have the link. Remember the hoopla when Spider-Man started the summer movie season in May back in 2002?
There are 37 major sequels coming out this year - that is a record number, and more than double the number that came out in 2006 according to Vox.
Not only are their a record number of sequels, but according to the same write up by Vox they are the lowest rated by critics ever - prior to this year sequels dropped an average of 8 points on metacritic from the original. 2016's average drop is 27 points.

So we have a record number of sequels and reboots, which are of a record low quality, the death of mid budget films

during a year with an extended summer movie season, where theatres are charging record high movie ticket prices and eliminating standard 2D tickets for more expensive 3D and Imax shows

Meanwhile, at home we all have 50" 1080p TV'S with surround sound and Netflix.
Lack of originality, lack of quality in the sequels /reboots, lack of mid -budget films that don't need to make a billion dollars to be profitable, lack of access to regular 2D films (personally I've not seen 4 movies this year because my local theatres only had one 2D showing a day, in the middle of the afternoon, and they are always sold out), record high ticket prices, and the availability of home theatres seem to be killing the box office this year.
