Eternal Sunshine of the Spotless Mind

I wanted a nice light-hearted movie between my night shifts, it started out this way, but about 45 minutes in I was all "WTF!?!".  This movie is pretty complex and requires some serious attention, but it's not overly hard to understand. You just don't want to miss anything.  It's a tale of lost love and the memories created.  In some ways it reminds me of The Discovery, but it's better.  I don't want to spoil anything, so I'll just say I recommend.
