I always thought this OVA is awesome and a solid 9/10. but after reading Rebellion, I couldn't enjoy it much like I used to in a recent rewatch.
Rebellion made this OVA so obsolete.

Rebellion is garbage and the only reason to watch the OVA is the amazing animation.

The ending brings it down to just mid in any version. You have to stick the landing after doing your loopty loops.
