Gameplay looks pretty damn fun and awesome to me.  The monsters were scary enough, but I'm not sure yet if I truly like their style.  I'll say, I rather liked the Mancubus, but disliked the Cyberdemon.  The imps I did like better than Doom 3's, and the atmosphere and levels I like better than Doom 3, though I did think Doom 3 did a pretty good job of feeling like "Doom" to me.  
There had BETTER be Spider Masterminds and Arachnotrons.  If not, I take it all back, the game will suck, and I won't buy it
