I'm aware this is a beta, so I'm going to REVIEW it as a beta.
Graphics: 3.75/5 There's really nothing at all special about this game graphically - the environments are average. The character models are average. The explosions and smoke are below average. I expect the disc on the 25th to look at least a little bit better than this.
Sound: 4.5/5 A lot of people are flipping out about the sound, and I do agree that it's actually really good - even without a headset or surround sound, this game is much, much better than any Call of Duty.
Fun: 3.25/5 Based on this beta, I'm not sure who'd buy this game. It's so full of glitches, after a single 8 minute match, I experienced two. (Randomly got an ACOG on one of my guns, and one time when I spawned there was a piece of scrap metal on my gun for some reason, blocking my view.) Although it's not the game's fault, I also adore having team mates that don't even attempt to do the objective, and when the defenders run all the way across the map to camp the attackers as they spawn. Sorry, not a big fan of that. DICE and EA promised a lot with Battlefield 3. Fans can only hope that this beta is virtually no representation of the final product - but if it's not, why bother releasing a beta that has so few similarities to the game being released October 25th?
