Yes, if they can get at about $150 million or whatever the cost is for the bigger and better effects, then yes, it will be better. Way better. But considering the low budget that the director had was very limited for this movie. People need to know that this movie isn't meant to be some kind of movie like, Starwars where they have the greatest effects in the world.. (maybe another movie would be a better ex. was just using it).
For the people who think its horrible, just keep in mind that it wasn't going to be the greatest thing in the world, at least they made the movie. They made it with a very low budget and that's fine. The next one will be even better if the director will get 150 Million with this movie to make the new one even better. With bigger and better effects.
