Check watchseries.eu to watch series online :) It's like youtube.com but it is composed of different series :) IT IS ABSOLUTELY FREE :)
Step 1. I recommend movpod.in
Step 3. A pop up will appear but don't worry about it, just close it.
Step 4. ENJOY WATCHING <3 (buff it first)
Series such as Friends, How I met your mother, Gossip Girl, etc. are all there <3
