I think both movie were mediocre. I at least i can give "The Giver" This. It actually kept me interested in what was happening. I did give two sh!ts about what was happened in Divergent. Every character was bland and boring. The Giver at least had Jeff Bridges and probably the best part of the film. There no really great actors in Divergent to relief you from the boring ones. Not to mention that Divergent was just a Hunger Games Rippoff and Shailene Woodley is no Jennifer Lawrence. And frankly think whole concept of the Hunger Games is stupid as hell. But Lawrence is able to make you care about what going on. Even with the nutty subject.
It's weird, when The Hunger Games came out, I saw it as a clone of The Running Man except with a teenage girl in place of Ahnuld... but everyone else seemed to think the Hunger Games was this bold original concept.
Then Divergent comes out and I don't think it has much in common with the Hunger Games at all aside from being set in the future and having a teen on a train ride, but people all claim its a "ripoff of the Hunger Games"
Then The Giver comes out and I don't think it has much in common with Divergent OR The Hunger Games (aside from all three taking place in a dystopian future and being marketed towards "young adults"), but people are claiming its a "ripoff of Divergent".
If anything, the films that remind me the most of The Giver are Pleasentville + Equilibrium. No recent film came to mind.
"Assignment" ceremonies seem to be popping up in other films about closed utopian/dystopian societies, as well. City of Ember (2008) with Saoirse Ronan and Bill Murray is another example i saw recently. And there's yet another film that I can't recall.
