1b66uu | china's role in world war 2 | We studied WW2 briefly in years 9-11 (aged 14-16) at school but it was mainly the European front. After reading on Reddit today about China having 15,000,000+ casualties I realized how little I knew about their role in WW2.
Any information would be greatly appreciated.

2rsmgz | why does hollywood insist on remakes and reboots? | I mean, couldn't they just re-release the film?
If they just did some marketing then ok sure, they may not get as much revenue but then they wouldn't have all the associated costs involved in developing a 'new' movie so wouldn't there still be a sizeable profit margin?
