Spoiler Alert...

I felt the exact same way. He kept saying that he found them there in that "land" or whatever inside the computer. But how would he find something already existing within something that didn't exist until he created it? And then to add to that confusion... At the end when he clapped his hands and made the entire computer world disappear, what was left behind looked like a deserted planet. Meaning there was a land there before he created that world. Which again doesn't make sense. I think this whole issue was the main thing that felt lacking in the movie to me.

Otherwise... I did think it was a fun movie to watch if you weren't expecting a tight plot line. haha.
