Estar/ser aburrido

Question

Am I right that (mostly) if I use it with estar it means bored and with ser it means boring?

Answer

Yes, you are right Emanuel.

Soy aburrido = I am boring (I am a boring person)
Estoy aburrido = I am bored

However, have a look at this other example:

Esta película es muy aburrida = This film is very boring. 
Esta película está muy aburrida = This film is [getting] boring.

At the moment of watching the film, you find it boring. This is expressing a quality to describe the film when you are watching it, as opposed to a permanent quality to describe the film.
I hope this helps,
