As to whether it's a problem...

I think it comes down to how you handle escapism. Everyone needs to remove themselves from their daily grind... This is evident by the presence of entertainment/entertainers in nearly all cultures in the world. Movies, TV, video games, drugs/alcohol, etc. are all methods of distracting ourselves... some are potentially less healthy than others, but all are potentially healthy to the degree that they allow us to temporarily distance ourselves from reality, which seems to be a regular human need.

I think any form of escapism becomes a problem when the person indulges in avoiding their inner conflicts more than they participate in engaging their inner conflicts.
