Disney’s live-action ‘Lilo & Stitch’ is a box office success, but online, fans are tearing into the remake for changing the ending—here’s the controversy, explained.

Nostalgia helped Disney's live-action version of "Lilo & Stitch" dominate over the weekend. There are some other Disney classics ripe for a remake.

For the most part, the new version sticks pretty closely to the 2002 animated film. The story centers on two sisters, Lilo and Nani, who are navigating life after the death of their parents. Nani, a teenager just about to head to college, struggles to hold down a job and watch out for her sister, who is a bit chaotic.
