I also use ReviewMeta and it does handle review hijacking. It's not a great experience as a customer, but if I combine ReviewMeta and Amazon reviews and search I still get pretty good products. My basic guidelines are that it needs at least 4 stars (preferably closer to 4.2-4.7) and the product can't be a "fail" on ReviewMeta. I also am wary if ReviewMeta is a "warn".
I don't trust Amazon reviews without a review checker anymore, they used to be much better. The highest reviewed products are often some of the worst. Any product with a 4.8 or better is immediately suspect (though some are fine, especially if they don't have as many reviews).
