The locations in the OT served two purposes. The first was to establish the reality of these alien worlds, the second was to underscore the themes of the characters inhabiting them. The Death Star as a hollow mechanical construct characterizing the artificial Empire, Dagobah as a miserable swamp yet with hidden secrets and powers as an analogue for Yoda, Cloud City as being both a heavenly refuge and hellish underworld...the list goes on.

The PT didn't really continue this tradition as far as I can tell. If it had, we would have first seen Coruscant as a thriving and enlightened city world, but we would gradually descend to its foundations and see that it was a city in decay, built on slave labor and lies, to suggest the true nature of the Chancellor and the decaying democracy. The clones would be grown by the Geonosans, whose own inhuman growth cycles would be adapted to the task of growing humans, and whose planet was constantly in a stage of starvation or unbounded reproduction. And Mustafar, while acceptable as a mirror of Anakin's inner turmoil, could have been changed to an orbital shipyard where the next wave of Separatist warships were still under construction. Obi-wan and Anakin could battle among the frames of ships being melted down and repurposed to serve the new Imperial machine.

I hope the ST gives us multiple angles of interpretation with their choice of location instead of just the sinkhole planet, the jungle planet, the water planet, etc.
