Well, uh...
I'll give it a decent rating because of the effort and the storyline. But, like SourMango said, since when was Samus some random British idiot? The voice acting could have been a little better, as could the animation (Megaman looked a little bulky, whereas Samus looks good bulky). For example, you could see the sprinting animation with Samus, but you can't see the legs. Same thing went on with Megaman in his Quick Sword form, except his arms weren't moving, which looks wierd.
