Runaway Lilac

I planted a Beauty of Moscow Lilac a few years ago in front of the porch for 2 reasons. One...I love them...the scent is quintessential springtime.  Two...to act a privacy screen. Well I basically let it go and now it's a tangled mess. Too tall, branches crossing this way and that, all growth on the top, bare in the middle, only a few blooms every spring.  So next spring probably going to have to do some drastic pruning...which I just hate thinking about doing.  But in the long run I will end up with a better looking shrub and hopefully lots more blooms.  This is what it looks like now.
