It was as easy to use as an official streaming service is, with integrated subtitles downloads in the background (from open subtitles), links to trailers and critics sites (it also pulled a lot of metadata from different sources).

Popular movies were always on top of the list because the default sorting was by seeders and these movies would load instantly

At the time it was the best streaming experience existing, paid or free combined.

[edit] oh and install was just dropping an all-in-one app somewhere on your computer and launch it.
