I liked the last C&C (3 I think it was). The gameplay was pretty much the same as in the older games, with the exception of some new tactical stuff (like the glider guys for NOD, awesome asset). The story was hastily put together which sucked, as it could've been very good.
The Scrin were something I first hated, but then I started to think about it a bit and IMHO it fits well to the story where the people have started to learn ways to contain the tiberium and suddenly BANG you got a new tiberium related threat in the form of the Scrin.
This new one seems to follow the trend of fast-play RTS' with no base building and resource gathering (well there is but it's kinda stoooopid). Clearly it's aimed for online play as was proved by releasing MP only beta and now this new DRM. And as I don't play RTS' online, the heck with them.
Just too bad the genre is dying, WH40k went titties up with Dawn of War II, never liked Starcraft so SC2 doesn't appeal to me (and it seems to be heavily MP oriented). If just the smaller game developers would have the funding and a good publisher to really finish their games this genre would do good.
