Lazily done? The CGI model for NX-01 rivals the physical model for NCC-1701-refit in sheer overthinking and fanatical attention to detail. Every single doodad on her was inserted with either a specific or then a modular-generic function in mind, to cater for all possible future plot needs. An all-new "look" was also introduced in textures and shapes.
That she happens to look like another starship design is hardly avoidable, as all Starfleet starships are decreed to look more or less alike for recognizability reasons...
Not sure that any hero starship would really suffer from fire coverage shortcomings. I mean, all those with the low-slung "Miranda" configuration do, more or less, as TPTB never install the extra phasers needed for truly covering the blind spots, but all with the "Enterprise" configuration ships are basically blind spot free from the saucer phasers alone. Except perhaps sometimes for small volumes within 50-100 m from the ship's hull, but if the enemy gets that close, then it's too late anyway.
