The only great part about the Universal Dracula is Lugosi.
I think Edward Van Sloan was good as Van Helsing, and I loved Dwight Frye as Renfield. The only Renfields I liked better were Tom Waits.
I also think that Peter MacNicol was the funniest thing about Dracula: Dead & Loving it with his Renfield, and I credit a lot of that with his utilization of a lot of what Frye did first.
Ugh I always forget how good Dwight Frye is in it. I guess its just Lugosi's presence overshadowing everything else.
