I watched a long ago on the TV but I don’t remember the year
The only scene I can remember is that there was this cute little girl sitting on a swing in the house garden, looking sad. At the background we could see the rest of what looked like her family happily talking. And for what I can remember it looked like someone was watching this scene from another dimension and by seeing the sad girl, the person decide to cross to the other dimension to confort her and as soon as he/she steps in ,that cute girl on the swing opens a enormous monster mouth and attack he/she and calls for her family to eat with her. It was something like a trap.
