- in terms of a specific episode, 'Aquiel' comes to mind. The 'shape-shifter' looks really dated - I'd love to see an upgrade on that.
Can't look worse than the shape-shifter in "The Dauphin."
As for the space-battles I disagree there. TNG was never about space battles, that was more DS9's MO. The Enteprise is an emmense
ship and shouldn't be potrayed as a fast-movinb barrel-rolling fighter a lumbering capital ship is precisely what it should be.
