I strongly recomend everyone to skip to 6
Each movie gets progressively better(well 3 is really shit, making no sense, having endless duex eux machina, complete mindlessness,more bad grammer than the others combined, characthers ooc,etc) but the first few are awful. The battles are completely mindlessly and hardly qualify as interactive, and the plot if pretty naff to. Maybe if your REALLY bored, but Im sure you can find something better to do.
6 is ok, but the boss fights are a little slow paced.
I guess one positve thing is the creator gets better with each one.
Oh and Fights with multple people in your team>fights with only one person. Seriously, fightd where you just press attack suck
