To put it delicately, Steam reviews have been...unkind to the new Doom's multiplayer beta. That's probably owed to the fact that it was developed by Certain Affinity, a studio that has done a lot of work on Halo and Call of Duty multiplayer maps, and why Doom's multiplayer feels like...well a lot like Halo and Call of Duty.
Thankfully, Doom's single player campaign is shaping up a lot better. In this hour long stream id's Marty Stratton and Hugo Martin demo two huge chunks of the game--one early on in Mars operations and another halfway through the game in Hell. It has a real 90s feel to it and it looks incredibly fast, which is more than I can say for the multiplayer. In particular I like how creepy and cult-y the UAC looks to have gotten, as in Doom 3 they seemed more like inept corporate goons.
That said I'm still a little concerned that half of the good ideas in this new Doom look like they've been ganked wholesale from the superb Brutal Doom mod for the 93 original. In any case, I'm far more excited for Doom now than I was coming out of the beta. May 13th can't get here fast enough.
