Books Vs. Movies

I am living my worst dilemma ever...
With more and more novels shot for the screen, I don't know what I should do exactly.
Should I wait till I have the time to read all these novels? Or go ahead and finish the movie?

In my heart I refuse the 2nd option, as nothing compares with a good book. And at the same time, I don't know if I'll have the chance to read the book(s). Apart from being expensive, I have a list sufficient to keep me reading for at least a year and a half back to back nonstop.

So,
Books Vs. Movies..
Tell me, what should I do?

PS: That was after I read about the release of "Love in the Time of Cholera" for screen. The Garcia Marquez' novel, that was -unluckily- on my wish list..
