Me personally do not like sites that destroy the usability and performance of the service through huge amount of advertisement like popunders, banners, fake links etc.
Movie4k has not low amount of ads, but because of it's age and popularity I put it on the first place. Movie Storm Movie Storm is maybe not so popular, but provides a good service.
Below I've created a list of movie sites that offer real stream links where latest movies can be watched online and absolutely for free. Alluc is a very popular site that was launched in 2006 and served as a streaming link-list until late 2014 where it was relaunched and became a video search engine that scours the web for links to free streams and downloads. Just Moviez Discovered this site just some days ago, seems to be rather new.
While it lacks the catalogoue style most other streaming sites go by, it's a unique approach that allows users who know what they are looking for to find anything available online in seconds. Even if it does not have the popular image, I put the site on the second place because of several things: good structure, very informative movie pages, nice and easy navigation, a big collection of streaming links for each movie sorted in a table and the main thing is - just few ads! Solarmovies Solarmovies is a site with rather many ads on the one side and with real streaming links on the other side.
