That Gametrailers review was good, but some of their comments were weird. They kept saying that the sword events were wasted potential because players could end up spamming attacks. Um, if this is something that is controlled by the player why condemn them game for it? The player has all control over their sword attacks and how do they use them. Once again, if the player is in full control why blame the game for a decision the game makes?
As for depth, not to belittle this game, but does anyone expect any depth from Wii Sports? The depth comes from the controls and what the game does with them. The events are basic, stripped down versions of real world events so why expect any big depth?
