It's been a while since I saw the original but I recall being amazed by the first battle.
The beautiful impact frames of lasers striking hulls, ships frames crumbling, shots of wreckages with rescue crew.
Not only do the cg ships look worse, but even stuff like laser volleys and explosions are all generic and lazy. It was pretty disappointing.
All that said, I expected as much going into this so I'm not feeling betrayed or anything.
