That's classic Hollywood thinking these days, whether it's a sequel, remake or a straight ripoff. Make the same shit, but bigger, louder and CRAZIER. So of course we got a new Death Star. A Death Star that is 50 times bigger than the old one. A Death Star that travels and shoots its planet-destroying laser at lightspeed. A Death Star that consumes entire stars to power itself up. A Death Star that doesn't destroy just one planet in the movie, but an entire planetary system. Bigger. Louder. Crazier.
Of course, when it comes to destroying the thing, it's an even easier job than before LOL.
Death Star Mark III along with I-Rex in Jurassic World is some of the laziest shit I've seen in blockbusters lately.
