I wonder how valuable crowdsourced electronics ratings would be.

Most consumer electronics reviews are absolutely dire: products reviewed in skin-deep ways by people who don't really have the chops and/or resources to review them in any kind of in-depth and meaningful way. I don't know if aggregating a bunch of crap reviews would yield more value or insight.

Whereas with movies, the ultimate test is just whether or not a person enjoyed the movie. Whether or not the reviewer is a knowledgeable cinephile I think there is a value in aggregating that.

There is also the issue of... relative performance and long term performance. To really decide if e.g. a hard drive is worth buying you'd need to benchmark it against its peers and perform longer term reliability tests. Reviewing a movie doesn't have those kinds of constraints.
