Went to see Coraline tonight. It was in 3D, which explained the unexpectedly high price and the glasses we had to wear (and they actually let us keep this time).
Coraline is a stop motion film where they used proper models, from the same stable as The Nightmare Before Christmas. I suspect some computer trickery was involved during some of the sequences, but overall it remained true to its roots in the real world.
The story, about a child who finds a parallel world which seems much nicer than her dreary real one, is well told with some genuinely scary moments (even for a grown up like me). But the real star is the world itself, which looks fantastic.
If you like a scary tale it is worth a trip. If you enjoy good graphic art and design you should definitely go.
