As for your original post - you're right to a certain extent. There are some people who have a vendetta against all things Oasis related (Cough US Rolling Stone Magazine Cough) exemplified in The Fly review (which simply bashed the band for the sake of it without really giving the musical output a chance).
But I think you're wrong in the long run. Noel was always seen as the brains of the band. When he walked, and Oasis continued under another moniker, not only did the press laugh but even some of us hard core fans on here were in denial. The Chief left, and the great song writer that penned the classic Little James was now taking over? Surely going to be diabolical. Then BTL was released, which was seen as refreshing but came as a shock to us Oasis followers.
My point? Beady Eye have already dissolved any overtly legitimate criticisms that would have been thrown their way because they surpassed expectations. Everyone expected them to fall right on their face. So while DGSS may not be seen as a classic, it will def. be seen as a success.
Also, one last point, while they may be nicking parts from other songs more blatantly - see The Roller - they don't sound like Oasis. It's much more upbeat and poppy. This notion would thus counter act the other criticism held frequently by Oasis haters - that they never tried anything different, that everything sounded the same.
While there will always be the Oasis/BDI haters and reviews, I don't think we're going to see an onslaught this time. Remember, Oasis' popularity was surging again from DBTT and DOYS after taking a mighty hit following BHN into the barren and uninspired HC years.
Frankly, I don't see this album getting panned by many. And even if it does, so what? Haters be mad.
