You can buy all kinds of necessities cheap on AliExpress for $1.99 or when they have sales every month for $1.79 this special section only available on there mobile app. Also most cities have food-banks or some churches giving out free food and clothing. There is also a Freecycle.org community kind of like craigslist but for free stuff.
Just didn’t have the same feel to the movie. Maybe if you never seen the movie it might be better. I find most remakes fail without at least some original cast.
