I've heard it was really slow and boring, like people kept saying it was a huge mistake to split it up into multiple movies
It was alright I'd say, although there wasn't a whole ton of stuff going on indeed. Splitting it into two is without doubt nothing but a decision based on profit - Pay full price for half the story! Twice! :D
It's really all just a cliffhanger piece with some character developments and story buildup for next years part 2.......
Also, I honestly predicted the ending like 20 minutes into it without having read any of the books XD
You know when she was so upset they saved her instead of Peeta and all? How she was so mad and wanted him back? I said to my brother: "Having no idea what will happen, I bet it'll end in one or another way with Katniss meeting Peeta".
