I found Diane Keaton's directing style to be truly dreadful... Sure, it's not a *bad* style and there's even a couple of really good moments in the episode (ones that absent BOB1 reminded me), but Keaton does something that I really hate to see in TP, she tries to imitate Lynch by *forcing* the quirkiness and the absurd... Lynch may show us something odd like the Horne bros. dancing when Leland enters Ben's office singing, but doesn't insist on that. We know Leland and we know Ben and Jerry so the scene may surprise us, but it's like it is... We don't need to see the dancing guy from the pilot more than a few seconds and it's only necessary a quick shot of a guy yelling "Hot damn this pie's good!!" to realize we're in a different place and to see Lynch's hand...
Keaton, on the other hand, insists over and over in the same kind of shots, the group of policemen and even does so in scenes where it's unnecessary... Lynch's quirkiness comes from the characters and plot and it's there, not fabricated (the Hornes scene again, Señor Droolcup,...) , but there's nothing quirky in a cop questioning Malcolm...
There are exceptions, of course, since Lynch is not by any means perfect... IMO he comits the flaw I'm talking about by insisting too much in Andy's "great moment in law enforcement history" from ep.8...
