"SHIIIIIIIINE, shine down on me"
I haven't read\watched all of the hellsing related media, but I heard a bunch of internet people say "Hellsing tv series sux shit. Watch the OVAs instead."
I personally really enjoyed the tv series, I especially liked that final battle between Alucard and Incognito.
I thought the ending song was pretty funny too. Make me feel so alive, shine on me, etc.
