I'm very unhappy that you are disappointed.
But, just as I think, you are not fair,
because the render on my computer takes 20 minutes. For FULL HD it's very fast!
To speed up the render, a certain work was done. You do not know about this, do not understand, but write such comments.
But this is your opinion and you have the right to do so.
All I can do, is recommend you use a modern processor and the After Effects cc 2017.
As for "complicated in editing" it's ridiculous)
All you need to do is insert the photos into the Placeholder_01, Placeholder_02, and so on.
what here can be confusing?

Be fair.
Good luck.
