If you really want to watch this for the first time, I highly recommend looking for the version with the Philip Glass soundtrack. Like Frankenstein in 1931, the original movie had no non-diegetic score, as it was believed to be too distracting for contemporary audiences. However modern audiences might find the movie stiff without it.
Also like Frankenstein, Dracula has a decent opening 15 minutes, a long lull in the middle involving rich people standing around while stage-acting, and a good closing ten minutes. Bela Lugosi, Dwight Frye, and Edward Van Sloan each do their best to carry the movie, and history rewarded them by type-casting them. Karl Freund’s work, well known for stylized camera movements, feels shackled by Tod Browning’s restraint. Browning’s own daring sensibilities on film went on to kill his career with the movie Freaks in 1932.
A childhood favorite, but I can see why it might fail to connect today.
