Arrested Development Season 4 comes to Netflix exclusively today, in another huge win for the service. If you haven’t been following the show, or have forgotten anything, O Canada has a great primer for the series up to now, featuring statements from the cast themselves: http://o.canada.com/2013/05/26/arrested-development-tastes-the-vindication/
And for Season 4 on Netflix itself, here’s the link: http://movies.netflix.com/WiMovie/70140358?strkid=536286740_0_0&trkid=222336&movieid=70140358
And remember, there are ways around the country restrictions if you’re not in the US.
Update: If you see watermarks, it’s probably part of a joke in the show, you’re not seeing a stolen copy on Netflix. Variety
