Gametrailers review, the major points I picked up on--Done my best to avoid spoilers, there's nothing plot or item specific in here, just the general statements they make about the game.
1) They mention the story is largely the same every other Zelda, when numerous other reviews say that the main story has been shook up and refreshed.
2) They then admit it's the most radical departure from the formula, and is quite challenging.
3) Fi gives you too much help and states the obvious--other reviewers mention she is one of the better helpers, never gives advice in boss fights unless you die, and is a well conceived character.
4) Great level design, but don't like frequent save points--again, other reviewers have praised this inclusion.
5) Now mentions the great length and amount of content--including side quests??
6) "uninteresting and confusing dungeon design"--in early dungeons. Despite earlier saying great level design??
7) Hardly any minigames--again, other reviews have said the Sky is an area with new and unusual mini-games to play.
8) "You either make your way through one mind bending room after another, or turn the machine off"--because of the lack of mini-games. Sounds like they don't like the fact the game continually challenges you, rather than lets you saunter through fields unchallenged or go fishing. Loses charm because of this.
9) Mix of old and new gadgets, all fresh and fun thanks to motion plus--favourite is beetle, very versatile. Finally, something in common with other critics!! Motion plus impressive but not perfect. Doesn't like new bombs control. Bosses are memorable.
10) Feels "creaky" when it comes to long-distance traversal--not sure why, explains important quest points are marked out and that there are numerous warp points to help you return to areas. Complains dowsing is a vague and too frequent part of the gameplay--again, something I haven't heard in any other review. They say "sprint should help alleviate slow travel" but then claim it's "muted" by the stamina meter--again, another element of the game almost universally praised.
11) "overall variety lacking" compared to other Zeldas, despite featuring inspiration from Galaxy, Mario Sunshine, Metroid and Sports Resort. Again, most reviewers I put any faith in (Edge, GamesTM, Metro, Eurogamer) praise the variety of the quest and set-pieces. Says the reward are the most challenging and inventive dungeons of the Zelda series--despite earlier on heavily criticising the early dungeons. They display "creativity few games can match". Apparently.
12) Completely utilises the Wii's potential--but no stronger than Twilight Princess (a GC game) from a techinical perspective. Water-colour graphics "gorgeous one moment, garish the next". Environments and Skyloft town "barren"--again, the game has been praised for its density, for Skyloft being an excellent, characterful hub in the vein of Clock Town. "It looks like an old game". Again, not heard this anywhere else.
13) Here's something--the musical instrument segments are praised as "sparkling". Most reviews that praise every element of the game have disliked or stated these segments aren't that great when compared to the rest of the game--Eurogamer in particular where unimpressed.
14) Most cinematic Zelda, but behind the curve--orchestrated music is great apart from some "ear-stabbers", lack of voice acting and "flappy animations" make the game feel like a "throwback".
15) Represents Zelda's first grey hairs, not moved on as much as other games in the last half-decade--but then says it proves tight level design, strong foundations and excellent gameplay trumps all: Apparently not the massive amounts of complaints you have about the game... Says there's a lack of whimsy and calls the game "business-like", which will frustrate or excite people.
Not one of the best reviews I've listened too--I need to shower so will return to this later with my thoughts and points from other reviews, but it seems like Skyward Sword could be a divisive game. It's also interesting to note how the European/UK reviewers are praising the game for shaking Zelda up and making genuine changes, while Gametrailers are criticising the game for not doing enough to change or for making changes in the wrong places.
