DE:HR/DX3 is a very good game for itself. But as it is the third part of a game series, the game press and players compare it to its predecessors. And all the great stuff that was in DE:HR was already even a notch better in part 1.
The Detroit and Hengsha/Shanghai maps were each about 5 maps stitched together, similar to part 1 and 2. But gaming has changed since 2000, there are action roleplaying games that are huge like Elder Scrolls (Morrowind, Skyrim, etc), Gothic/Risen, Witcher, etc that have all huge maps with usually seamless worlds packed with a lot of hand placed quests and side plots. So yes, DX1 was dense and had big maps but DX 2 and later had tiny maps with even lower density plot and stuff placed in there. In DX:HR/3 there were just a handful of NPC persons wandering around each map in cities like Detroit and Shanghai. Come on in we know better with games like the above mentioned and Grand Theft Auto, Assassin Creed or Watch_Dogs. A new Deus Ex needs bigger seamless maps with more interactive items (DX3 felt very static in comparison to its predecessors). A DX game based on e.g. the Watch_Dogs engine would be a great start.
Unfortunately many players played the first two games later when the graphics already looked dated.
