I'm kind of with you on this. The weird thing is, the nostalgia factor relates to the Senators of the 60's - mostly awful teams and a franchise that bolted after barely a decade. Having nostalgia for them is kind of like having nostalgia for the '07 Nats or something.
I'll go one further and say that I don't get everyone's fascination with script font in general, whether it's the curly W or the away unis. Script font is so unimaginative. When I think of the really iconic/excellent team insignia - Yankees, Red Sox, Pirates, Tigers - few of them use script font with their signature look.
The dc block logo is worse, I like the old senators w with straight lines
