Strengths and Weakness's of previous work

I looked at previous work, which helped me identify the strengths and weaknesses of good and bad film trailers. 


Some of the strengths are:
-Camera Shots
-Good use of Music
-Good use of Fonts
-Production houses involved.

Some of the Weaknesses are:
-Doesn't show Narrative very well.
-Music is too loud so cant hear the  talking.
-Different volumes of dialogue and  difference locations cause echo,
-Fonts dont fit with Genre
