Overview of 123 Movies Add-on and Kodi 17 Krypton
123Movies streams movies and has a nice setup such as Most Viewed, Most Ratings, Top IMDB, Genre and more. So far in testing it is a good add-on and works well with Krypton.
The streams are reliable and work well. It also has a one-click-to-play interface so no having to look through a big server list.
Be sure to have the Unknown Source box checked as Kodi 17 requires this before installing 3rd party add-ons. Read Here for how to Enable Unknown Sources option.
