There are many online documentaries and evocative readings of the individual poems that students can watch as homework or response triggers.
I have given some that I have found useful to prompt class discussion and sharpen interpretive response. Having students prepare their own readings of some or part of the poems can also prompt closer 'ownership' and empathetic connection with the combatants that Owen speaks of and for. James Wheller for example, gives an insightful rendition of 'Dulce Et Decorum Est'.
The Robbie Ellis clip offers a moving rendition of 'Anthem for Doomed Youth' and another poem that explores the resonating horror of W.W.I. and war itself. Although the second poem is not one of the set poem, it works well to prompt what makes Owen's anti-war poetry so powerful.
I hope they assist your evaluation of Owen's verse.
