I enjoyed it too, especially the cutscenes and epic team ups. Who knows, this could still be epic.

That level looks like something out of Rayman, but no way that's what it could be! Also I'm guessing the Adventure mode will be like that of Melee, which is unfortunate as I loved the cut scenes in Sub Space Emissary aswell, but eh I'll survive!

I´m getting a Luigi´s Mansion 2 vibe from the screenshot.

Looks rad.

the gloomy athmosphere and the prevalent green in the pictures screams LM to me

"This is the Luma Shot, which highlights the different ways to control your Luma. You can switch between controlling the Luma alongside Rosalina or away from her."

"There are many changes being made to attack and defense options for grabbing edges. In this picture, Link is actually trumping Mario's grab."

I gotta be careful or I'll miss some info. Sakurai is making a habit of posting additional information on Miiverse:

Some other changes include:
-Air time and accumulated damage will determine your period of invincibility while hanging on an edge.
-Grab controls will no longer be affected by whether you have above or below 100% damage.

What I think this means is that strategies like constantly jumping and grabbing the edge will be nerfed by making the character invincible a very short amount of time if the air time is short.

Mechanics are so much more important then characters..... so why are they so boring to talk about?

It's harder to talk about because until we experience it we won't know exactly how it affects gameplay. From what I can figure out I think the changes announced will be beneficial to the Smash experience.
