The richard eyre one (bbc 1998) is mainly family/psychological BUT also has some feminist qualities (so i'm using it for both). I'm not sure if youve done it, but the main feminist ideas are..
*Cordelia is portrayed as more strong-willed and defiant, firstly in that Lear comes to her (instead of the other way around) at the end of the table, and she shows good judgement and no intimidation in her leaving remarks to her sisters "i know you... what you ARE"
*Characters of goneril & regan built up more, so we can sympathise with them rather than see them as purely evil - lear arrives at gonerils house with 100 rowdy knights, who trample all over her white house with muddy feet, then lear enters, shouts "dinner, ho dinner!" and therefore lear's harsh curses to her when she tries to tell him of for his behaviour seem a little uncalled for, and she breaks into tears, allowing audience to sympathise..
not great points for feminist, but theyll do for me! good luck!
