Pros
Pro Hollywood approved
Lightworks has been used to edit movies such as Wolf of Wall Street, 28 Days Later, Pulp Fiction, The King's Speech and many, many others.
Pro Highly polished editing workflow
Lightworks is very focused on just the editing workflow. It's full of functionality that eases the workflow. For example, media manager can be used to storyboard, "mark and park" can be used in timelines, cut points can be adjusted in 3 ways (end point of a clip without adjusting the start point of a clip that comes before it, start point of a clip without adjusting the endpoint of a clip that comes after it or start and end points of 2 joined clips at the same time) without shortcuts, just intuitively placed mouse hover points around the cut point. Such attention to detail is what makes it an efficient tool for editing.
Pro Fast, light, best option if you only need some light editing like cutting the video
