I like it, but I don't like that I can't move my mouse or else the summary will fade away..

The movement that is Web2.0 is keeping information easily accessible and integrated into a simple pretty interface, and while it's not particularly difficult to click the "full summary" link on an IMDB title, the same could be argued with all functionality on every webpage. Having the information needed accessible all from the main title page without causing any loss of space or functionality of the title page is what makes this an extremely useful and important script.

My only issue is with the IMDB redesign scripts causing the text of the popup to be white whilst leaving the background light yellow. Unreadable.

Does what it says seamlessly.
