This is a legal site, it is even listed in http://wheretowatch.com/where-to-watch

It has a bunch of b-movies, public domain flicks and such. This one has a variety of plans, free with ads, monthly subscription, and rent (pay to watch). I'm just interested on the free category.

Uses JWPlayer ads edition.

They went over a web page re-design, during wich the free section was not available. The good news is the free section seems to be back, and the page still uses JWPlayer ads edition.
