Don't Waste Your Time . Uneven, choppy direction and convoluted plot marr the otherwise superb story and excellent performance of the uncomparable Meryl Streep.  Unfortunately, not even the fabulous Ms. Streep can save this -- recommended for devoted fans only, bent on completing their Streep collection

Ex Output:
NEG

Appalling . I waited to receive this copy from the US,and when I checked it out it was very bad quality.Thick of the worst video you have,and I think you can understand.I certainly won't be buying anything off this studio again.I do recommend dvds from Red Sun,Hong Kong Legends and Vengeance Video are ok.  The film is a masterpiece of classic kung fu,but the quality is dire.I hope Red Sun release it

Ex Output:
NEG

Great film, lousy DVD . I'm really tired of the shoddy DVD manufacturing used by many studios and distributors.    This is a great film.  I have it on tape.  I was thrilled to see it'd been released on DVD.  I love Italian knock-offs of American films (STREET LAW seems inspired by DEATH WISH), and I'm a Barbara Bach fan.    So I bought this STREET LAW DVD brand new, as soon as Amazon offered it, without waiting for the price to go down.  I unwrap the pristine-looking DVDm pop it into the player, and after a few minutes it pauses.    Then it pauses again.  It pauses constantly throughout the film.  I mean at least once a minute, often several times a minute.  Pause, pause, pause.  Most of the pauses are brief, some last several seconds.  I eventually took out the DVD, cleaned it, but it didn't help.  I suffered through 50 minutes of this film, then gave up.    VHS was a decent format.  Tape had problems, but nowhere near as bad as DVD, with all the skipping and scratching.  (And Google "DVD rot" -- see what comes up.)      Still, changing formats is a great way for studios to resell us movies we'd already bought, so I guess it makes sense for them.    I don't know whether I got a bad copy of STREET LAW, or if this DVD is part of a bad batch, or how widespread the problem is.  But beware
