Review title: It didn't work for me! Product review: I hate to say it, but purchasing this product was a complete waste of money for me. I have a water tester and after installing the filter per instructions the ions in the water did not change . . . at all. This filter just gives the appearance of filtering the water when it actually does nothing. So, it's doing nothing for me but collecting dust!

Review title: MPAA - Give us a break! Product review: This is a favorite midnight movie for my 30something generation. Problem is, this is only half the film it ought to be. There is an alternate version (which you might be able to track down if you have relatives living in Greece) which is a WHOLE LOT BETTER.Dennis Quaid and Ellen Barkin have a relationship that you care about, several odd continuity glitches suddenly make sense (once you realise what they had to cut out).DVD was made for putting movies that got hacked apart back together. Even if the missing parts just get offered as 'EXTRA MISSING SEQUENCES', they ought to be there - especially for Zone One.
