I also noticed that a few people whom I know did not like Serenity, really enjoyed LH
Was kinda the opposite for me. I like Serenity and wasn't at all expecting to like LH. Having played through it I can also say that I like LH quite a bit more than Serenity. Can't really put my finger on why though.
Looking forward to future updates to both, especially since crossovers appear to be a thing!
