Well if you really didn't like the tutorial, you probably won't like the full game. I thought the demo level, and the ensuing couple of hours was merely pretty decent. However, the remaining 15-18 hours are pretty amazing, epic and enjoyable.
To sum the game up and 'sell' it to you, what LoS offers is a lenghty, action-packed quest which actually feels like an epic journey, packed with some of the best boss fights in good, long while and some truly gorgeous visuals and music. The game is technically ragged in places, and some elements of its design (weird camera angles and sketchy platforming) frustrate, but overall this is just one of those games packed full of memorable vistas, bosses, tunes and 'moments'. It's one of those games which reeks of the love and passion of its creators, its one of those games with enormous replay value, and its one of those games which, although its far from perfect, will be fondly remembered for years to come (mark my words).
Or, you know, THIS.
