ME comics from Dark Horse: worth the purchase?

I've been considering buying the ME comic bundles (Invasion, Evolution, Redemption), but the Amazon reviews are mixed. Some complain that Liara is uncharacteristically portrayed, which is a bit of a turnoff for me. I searched r/masseffect for discussions on the comics but didn't find a whole lot, and everything I did find was an old thread anyway, so I thought I'd bring it up here again to get peoples opinions.

Are they any good? Also, is there a preferred reading order, or are they all stand-alone?
