Sure, I think so. There's always going to be complaints about every awaited game, because everyone has "Is it worth it" thoughts and look for the negatives. Sure, the physics may not be the same as GT5 or FM3, but they're sure as hell better than TDU1 (speaking from an X360 player, can't speak for G25 use).
The graphics are great, the day/night cycle is a nice aspect, the cars are detailed (with better sounds than the first TDU, but again, not GT5/FM3 level), there's a lot to do, a lot of furniture to furnish your house with, a lot of houses, a lot of cars, a lot of clothes. I think it's great, but if you're looking for a simulation (which appears to be what a lot of TDU2 players with complaints are looking for), then look past TDU2. If you want a huge, open world, with lots to interact with, lots to do and lots of places to go, then you shouldn't be too unhappy with TDU2.
