Just finished it. Loved it. The dreamscapes were pretty cool, I like hearing the studio chatter, some of those songs are a blast to sing. Probably going to go back and play on expert.

I love the few songs I have played with it so far. The presentation is top-notch and the songs are great to sing. I only played "While My Guitar", "Dear Prudence" and "Eight Days a Week" so far because I didn't have much time to play today but it is a lot of fun. I am planning on playing the campaign over the weekend and getting the Day Tripper achievement without killing my school work time.

Why would this not feel like Rock Band 2? 
  
The title of the game is "The Beatles: Rock Band" 
So it's The Beatles in Rock Band...why do some people seem really surprised it's a Rock Band game? 
Especially reviews that say it should have has this from GH5 or that from RB2. 
It's RB plus Beatles, everything else is did you have fun? Is it designed well? 
 
End mini-rant.

The lack of Billy Preston kinda bummed me out, but loved the game. Got my day tripper achievement pretty much in one sitting.

The game is exactly what I had hoped for. Played the game strait through on guitar/bass+vocals right when I got home from school and got that Day Tripper achievement. Going to go back and play it on drums to get all the photos and take a little bit more time going through all the little details next.
 
The 45 song setlist has kind of already bothered me, though. I thought 45 would be fine at first, but now that I actually have the game I kind of feel a little cheated, but, thankfully, there's downloads on the way. I also noticed that there's not really enough variation in which people show up in the background...I swear I only counted like two character models total of screaming girls (I'm talking the closeup views here), but it's still A LOT better looking than the normal Rock Band audiences.
 
Great game, still. Can't wait for Saturday when my friends and I rock out all day to The Beatles.

" I just got this this afternoon, and played a few songs. It seems soild, but its really is just Rock band with a bunch of beatles songs. It has its own style and the story mode progresses in a nice way but it feels just like Rock band 2.   What do you guys think so far? "

I like it. It's not the most amazing game ever, its a reskinned rock band 2, but its made with such love and attention to detail that makes it stad out. Nice stuff
