All the peoples who work on this movie have my respect concerning the special effects. It is a very hard work, a team effort to create something very clean.
BUT and holy cow, it is a big one :
What the hell the producers do ?
In the coming lines i will explain THE ABSOLUTE rules to follow to do a movie even with a poor budget, and it will look like pro.
Any movies who follow these rules will work.
1 - 25 or 24 fps NEVER EVER do a 60 fps frame rate.
It is for video game and even video games for 3d cgi use 24 fps.
60 fps looks plastic.
2 - always exaggerate. Motion blur and moves.
3 - use focal and blurts into explosions - blur into movement
4 - if 1 effect looks cheep into the middle of 1000 who looks great, redo the effects or everything will be lost.
5 - musics and bgm need to follow action, need to be 50% of the action, do not put a music over the top it will not work, or do it for less 2 minutes to a special shot or scene. If the bgm are bad the movie is bad. If the OST are bad the movie is bad.
6 - stupid characters, cliché acting, over reaction and sunglasses by night are for comedies not for serious apocalyptic movies.
And you know what ?
Producers DO NOT FOLLOW ANY OF THESE RULES at ALL !
They do the exact opposite.
And this is why a movie who cost millions and have a not so bad story, looks like a end of studies' project.
What a waste of money.
