If it doesn't feel like trek it will not matter in the least. It's the whole point, to get rid of the old feel even if it's temporarialy.
Can it do worse than Nemesis. (Thankfull) No. they can't do worse. They're activating a very agressive designed advertising scheme no Star Trek Movie has ever had. It will be the most sucessful Trek Movie in History.
Nemesis was boring and foreign.
