Fantastic movie... I raved through the mid 90's in the UK with Jungle and Happy Hardcore tunes so I know the scene very well (was DJ aswell at rave parties). The movie, even though they portrait the rave scene from USA is still pretty accurate with what goes on at illegal warehouse parties. If your like me, an old school raver from the 90's you will enjoy this movie.. This movie came out AFTER the classic / cult rave movie "Human Traffic" in 1999.. I soooooooo wish to go back to those times.. If you like your old school jungle / house / techno then you want to watch this movie Groove... have a few beers to loosen up, because the sound track to the movie is unreal and you will be dancing in your living room !! movie 7/10
