It usually takes some time before a language learner is able to follow a movie in their target language. You have to be able to recognize the words being spoken at a natural speed and know their meanings. It can be frustrating because you'll always feel like your playing catch up. 

At the beginning, I used to always watch Spanish shows with the Spanish subtitles turned on. Reading the words as they were being spoken helped me a lot with my comprehension. I would recommend watching movies that sound interesting to you. You can always hit pause if you have to look up important words. Eventually, you'll find yourself stopping less and less. 

Michael's suggestion of watching a movie dubbed in Spanish that you have seen many times is also a good idea.

Great article Carlos! 

In the US, phrasal verbs are a huge part of our everday conversations. If you do a search, you'll find a bunch of common ones. Here are a few:

Off the top of my head: refers to what can be recalled in an instant without much contemplation

Take care of: means that you will assume responsibility for a task, person, animal, etc

To break down: to give a detailed account of an event, situation, task, etc 

To have a break down: to become weak emotionally or physically

As far as online goes, I haven't come across any good sites for streaming Spanish movies or shows. I know Ebay has a ton of affordable Spanish movies. The difficult part is finding the ones that were originally recorded in Spanish. It definitely helps if you have a few favorite actors. It'll make your search for content a little easier.
