I don't know if it's John Barton's edit/adaptation or Trevor Nunn's direction (probably a bit of both,) but this trilogy version of
The Wars of the Roses seems to be a lot less overtly Lancastrian in sympathy than Shakespeare's four-play original. Not that it's become Yorkist instead, but both sides of the conflict come off about equal in terms of culpability for the lives lost.
Richard III is by far the most frequently performed play in the tet as it's considered something of a standalone story, but it definitely benefits in a couple of ways from being seen in context, and one of these is in a titular villain who isn't quite as villainous here: Robert Sheehan's Richard spent
Edward IV as the Yorkist enforcer, doing the dirty work that'll get his family into power. Once they've got it, it turns out that the biggest obstacle to keeping it is the family themselves, so he proceeds to turn on them, killing both relatives and former allies.
