Which template to use?

hello guys, I purchase this WD 3 days ago I wanted your help,
I would put the posters by Thumbgen but I do not know that I have to use the template.
Use the default theme on the WD

I would like to manually put the posters to the movie because the WD I was fine.
I do not understand why the film with sequels do not put them in order
then puts Alien 4
Alien 2
Alien 3

then do not even understand why not put the movie ratings
and most of the films in the row Total time is written N / A

one thing I’ve also noticed I am also in possession of the previous WD
them in wax posters is written if the movie was in HD or not here does not give any information regarding this.

sorry for too many questions …
