Most problems arise from it trying to be a new entry point to the series, which ended alienating some people. Also, mon design is terrible in comparison to gen 4, which if it held the same quality, or they even had reserved gen 4 designs for Unova, it would had been more loved.
Another problem is type distribution across the game, there is not many good option to build your team (namely it takes forever to find any Electric-type that isn't Zebristka or ANY water type). Too much gameplay is post-game, which again brings back the annoyance of grinding to E4.
