Despite being a little rough and unpolished, Rise of the Argonauts is one of the best action RPGs consoles can offer
Also, the script is great, with so many well written lines and deep, thought-inducing phylosophical considerations (maybe too deep for some reviewers, I guess). The characters are all great, there isn't a single annoying character throughout the whole game (the same can't be said for some bigger productions). If anything the combat itself is a bit dull at the beginning, (but quickly gets better as you gain new powers) and the whole production could have used some more polish (some animation issues and a few bugs that should have been addressed), but I can't find any major flaw that justifies the reception this game had.
If you're looking for a no brainer hack-em-up go play Ninja gaiden or something like that, cause you'll hate this RPG, but if you like the KOTOR/MASS EFFECT/JADE EMPIRE dialogue mechanic and would like to get involved in a deep, beautiful story with great characters and good real time combat, do yourself a favor and buy this game, you won't regret it.
