Star Ocean EX isn't a horrible anime, but it's bad. It could also be a matter of perspective, because I don't think Star Ocean EX was made for anyone over 13 years old. Here's a brief look at the story. Claude is on his first interplanetary mission when his space ship he's on runs into a asteroid field. After making emergency maneuvers they land on a unexplored planet. Claude sets off on his own and finds a artifact which he accidentally sets off and it sends him to another world. He's at the other world where the first thing he does is save a young girl named Rena Lanford who thinks Claude is the legendary warrior who has come to save the world.
Ok I think that's enough. The story I think was written for a ten year old. The animation looks like it was made in America. The characters are cardboard cut outs with no personality. The music wasn't very good. Overall it's a cheesy anime that I think wasn't made for anyone over 13 years old.
