Depends what you like in a game
I've just started and I'm really enjoying it - as the reviewer says, I've laughed out loud a couple of times already. I like the humour and the steampunk feel. +1 as well for making the ship interior as much like Firefly as they thought they could get away with.
Yes, the devs have played it fairly safe, but it seems a good all-round package to me. They do have some innovations, such as having "negative perks" - for example, when you're min/maxing, you can lower your intelligence to the point where you "gain" the "Dumb" attribute. The game is then flexible enough that you'll get appropriately thick dialogue options to choose, which can flummox people you're talking to.
Can't comment much on the Companions yet - although I disagree with @Rites above: Parvati actually expressed a clear opinion about which option she preferred in one of the quests, so they're not completely passive in that sense.
However, whether you enjoy it is going to depend on whether this is your kind of game (obviously). I've read criticism that it's not combat-heavy enough, for example - but if that's what you want, then don't buy this, go and buy COD or something. It's also not huge, which is a plus for me but obviously a minus for others (who I guess have more time on their hands).
So, it's personal taste of course. Read the reviews, work out whether it's for you. I'm loving it so far, YMMV.
