The sessions are changing and so are society itself. Everyone feels that they are reading the same books because of the constant use of traditional material being reformed, playing the same video games because the best games are either remastered, continuing an old series , and reuse material (Pub-G) is one of the known factors, and films is following in the same category . Industries wish to please their audience with a taste of the good old days of remastered films, and returning television shows; but still for this modern age it doesn't count as being original at all.
I shouldn't forget about music because that is known to be one of the most catch industries of knowing to reuse material and that all music sounds the same. There is no lie that major traditional industries are catching on to the phenomenon. They are in need to please their audience's thirst of new non-traditional material. Because if they don't, people will get bored.
