There is little more subjected to conditions than love.
You can't truly "love" someone, unless you know them as they are, respect them for who they are, get along with them to at least some extent, and are able to accept and not be too bothered by their faults.
If you feel your lover/partner/mate/whatever your prefer to call him/her is without faults then you do not see them as they are. This is evident because of the undeniable fact that no two person's are the same, and no human being is ever "perfect".
Love is also fickle, and constantly changing, evolving. The blaze of blinding passion simmers to the warm, enveloping loving bond and friendship that can take a couple far into the future if sustained and cared for.
As such, I don't think "love" can be anything but subjective, and that your appreciation for a movie or a thing is not a matter of "love" but a matter of just that, appreciation coupled with enjoyment and liking, but not love.
