I can understand several of the critics here; sure the game does not look impressive and it is a shame that it recycles some assets from Star Fox 64 3D. It is going to be the great problem of the game, but I hope they'll polish the graphics all they can anyway. With that said...
I think it's curious that those who watch the gameplay from home find it slow, boring and easy, but those who have actually played the demo say that they felt overwhelmed by the controls and in the footages we can see several people who keep crashing their arwing against walls. The low number of enemies in the on rails section of Corneria (that can't be applied to the all range phase) it's due to it being an introductory level that teaches the player how to use not one but three new control schemes (something we know that needs some time to get used to). In addition, if we compare the treehouse footage with the showfloor demo we can see several enemies removed in the latter.
On the other hand, I find it hard to believe that missions like Titania or Sector Alpha can be considered slow or boring. In those, there is shit happening constantly in the background, the level keeps introducing new hazards and obstacles during all the mission and the quantity of enemies is the usual in the series.
I can understand better the complains about the gyrowing and the walker. They still have to sell me those, because Zoness and Area 3 DO look slow and empty. However, once again both are missions that introduce new vehicles, so I find logic their pace. Anyway, I think the walker can add a lot to the experience (like that alternate way to destroy the Corneria boss, or the navigation through interior segments), while I have my doubts with the gyrowing, which looks original and fresh but out of place in an arcade game.
About the retelling of the story and the recycling of situations and environments... I assume most people is talking just about the on rails section of Corneria (intentionally built to resemble Star Fox 64), right? I can't remember situations or scenarios like the tower area surrounded by spiderbots, and it is obvious that the giant flying fortress boss is brand new. And yes, Titania is still a desert and you patrol it searching for a lost member of your team, but apart of that I can't see any similarities with the original mission layout, enemies or hazards from SF64. In addition, Zoness is nothing (nothing) like the original and Area 3 is a new stage with new situations and environments. Yeah, most of them are the same planets, but Star Fox Assault used Corneria, Meteo, Fichina and Katina too and I can't remember any complains (about that).
I understand though the fears about the story being the same of Star Fox 64 (Starwing, actually) one more time, because this is obviously the war against Andross in Venom again. But we have seen Pigma attacking in solitary, a giant mecha-gorilla in a space colony, evidence about that same colony having crashed in Titania, Katt being a prisoner in a Zoness base, the Corneria boss surviving and escaping on a rocket and the destruction of a space cruiser from the inside, which are all things that I don't remember at all in SF64. I'm sure there will be moments taking inspiration from the past (like Peppy being lost in the desert or the missiles attacking the Great Fox... and I bet there will be a train in Macbeth), but the development of the story promises to be different enough not to consider this game a remake. I think it will be something more like Metroid Zero Mission (GBA) or Punch Out! (Wii), which is fine to me.
