Um…..
The cover's that usually are from different artists, and even then, what's inside is the same thing, It the matter of CHOICE.
While here, it literally WAS a TV movie that was just thrown into the theaters, many times it faded to black, basically saying "This is where we cut to commercials." And that it was only in limited theaters, and even then, the theaters may have not even announced that they were showing it at all! So to the people who WANTED to see this movie, COULDN'T If they didn't do enough research on what they're near by movie theater was doing. Because I could've went to my theater on June 16th, but they were only showing it on June 22nd. If I didn't stumble across that Info.

It's mainly because the only reason it was made at all is to give context to a spin-off toyline that came out of nowhere, and said toyline appears to be rather quickly slapped together, with the apparent goal of leeching off similar toylines from other companies.
