Ehhhhhhh...
The Shadow Chronicles OVA was...well, it was tolerable?
It really felt like an incomplete product, even accounting for what was only supposed to be the first installment in a new series. Like if they only did the bare minimum of lore research, never mind tie-in. Barely anything from the Sentinels saga, which should have been a bigger influence and narrative device considering the reinforcement fleet wasn't like Mars or Jupiter Divisions (ie from outlying colonies), but from the Expeditionary Fleet and the Sentinels Alliance themselves. And the Halcyons' betrayal? Hoo, boy, was that going to be a rippling clusterfuck in terms of consequences to the Alliance...
Or the ramifications of the Neutron-S warheads having been authorized for use on Earth! Those all should have been at least acknowledged in-universe, but it's entirely glossed over.
Redo TSC, if nothing else.
