See it if You want to see a performance of the effects an apocalyptic event can have on humanity. You like simple staging.
Don't see it if You need elaborate staging. You can't sit back and have an open mind. You only like plays about real issues and not what if.
See it if you liked Lord of the Flies or post-apocalyptic philosophical plays in a modern setting, well acted and performed in an imposing room.
Don't see it if you don't like mildly interactive theatre, or need plays to have clarity in plot and premise, however well-intentioned, directed or acted.
