Egyptians wished for a new or improved constitution, they wished to depose Mubarak. who controlled both the military and the security service, they wished for free, open and fair elections. They accomplished most of that until Morsi was elected, just because he got more votes than other candidates and not because most Egyptians voted for him.
Morsi set himself up above the constitution and unilaterally altered it, and so although Egyptians achieved a better constitution before Morsi, Morsi took that away and as a result, the largest protest assembly in the history of the planet took place at Tahrir Square, and the military intervened and Morsi factions proclaimed that to be a coup, regardless of the demands of the protesters to depose him.
Some of what was achieved, was also lost. There have been accusations that the military still has Mubarak elements in it, but what's causing the most atrocities are the security services, not the military, but the U.S. apparently makes no distinction because it has now cut support for Egyptian military.
