In short: wonky physics, weird (but not game-breaking) bugs and glitches, a decent car list with pretty good customization, decent graphics, and an amazing world.
The handling of the cars in The Crew has improved much since release, but is still really weird. However, after a few hours of driving around, one will probably get used to them and can work with them.
The glithes mostly consist of cars (especially Dodges) getting launched into the air or stuck in random places (can be fixed by fast travelling), and are mostly more amusing than annoying in my opinion.
The car list is not great, but contains decent variation and the customization with different specs for different things is a surprisingly good way of doing car classes.
The graphics are nothing amazing but still decent as of right now (may 2017).
The game world of the crew (literally the entirity of continental USA shrunk down) is the best I've seen in a racing game so far, and aside from being huge, it's also full of details and hardly ever repetitive or boring. It has great variation in landscapes and is, in my opinion, just a nice place to be.
The storyline is one of the best ever in a racing game, E.G. absolutely terrible.
