Since several more "glowing" reviews have appeared in the last day or so, I dashed off a note to Amazon.com about them. I included links to the most suspect reviews. I didn't include them all, since several of them could really be from people who honestly are that blind.
I'll post the result. I don't want to post the message I sent until they respond.
BTW: I would encourage everyone here to not only rate those suspect reviews as unhelpful, but report them as inappropriate, too. There is clearly a scam going on here, and, as home theater aficionados, we need to help others make a truly informed decision about this product. Sending off a polite, but concerned complaint email to Amazon would also be helpful. If they get enough of these, they can't continue to ignore us.
I'm personally sickened by this. As someone who loves movies, this situation is unacceptable to me. I'm not normally the crusading type, but I think it's necessary in this case.
