Edit: Sorry about that, somehow the server issues causes a double post.
Already gave my opinion, but now that I have time again, I will put it all down here.
The graphics are okay, they look really good when you turn on all the special settings, but look more crap then normal if you have to play in low to medium. Everything just felt blocky and underwhelming on the lower settings, even my fire blasts felt more like I was throwing red water balloons. I think I am just spoiled by WoW. WoW does not have "high end" graphics, but they make up for it with a "consistency" that comes through no matter the graphic settings, CO didn't seem to have that.
The animations are clunky, I kept feeling like I was "sliding". This has the nasty habit of taking me out of a game, since I no longer feel like I am part of the world, but instead superimposed over it. The creatures you fight had the same issues, often sliding around at me.
The way they handle the mob sight distance is also annoying, at least at the graphic level I was playing. I noticed when I got close to a creature, but not close enough to fully see them, that they would just be a black shadow sliding in the distance. Mind you, the background wouldn't be black, just the creatures standing around. This looked silly to me every time I saw it, and really took me out of the game.
Combat itself felt clunky and unresponsive. I would sometimes hit my hotkey and nothing would happen, or I would click my auto-attack only for it to accidentally unclick so I would just stand around some more. Fighting enemies also felt "slower" then I am used to, with some of them taking like 20 strikes to the face with fireballs just to take down.
It is not all bad though.
The character customization is very detailed. I don't think it has as many "options" as CoH, but I do think it has more creative ability, to really adjust every little thing about your character. I was able to make some impressive looks. Other things I like is that certain items you add to your character actually are used based on your travel form, so if you give yourself wings, your wings will spread out and flap a bit when you fly. If you have rocket boots, they will have a little flame effect coming off from underneath them, etc.. I liked the customization.
The power sets are very detailed, allowing you to be anything from a ninja, to a hulk, to an iron man, all with unique powers that overlap at first but seem to get more detailed later. I had so many options I had trouble choosing what I wanted. I ended up making my first character a pyro.
Instances looked like they could be very interesting based on the few I tried, and I like that the game seems to throw in some cutscenes now and then. The way they get you into the story was also cool, since you just start out with alien invading, rather then just being a green hero going to beat up some thugs.
I love the fact you can customize powers, and the large amount of travel abilities that you get early in the game. I was flying around on fire when I started my character, and was even able to change the color of the flying flame from red, to blue, to pink, if I wanted to do it.
In the end I don't think it will hold my interest. I am very ugly when it comes to graphical consistency, and I feel the look of the game, while great, got a bit difficult to absorb at my graphic level. Maybe when I get a better computer, that will change, but not yet.
