Hellsing

The Hellsing watch order comes down to two entries — the original 13-episode series first, then the 10-episode continuation. Start with Episodes 1-13, the 2001 GONZO adaptation, then follow with the second entry, Episodes 1-10. Because these are the only two installments, the correct order is simply the original series before the continuation — there are no movies or side specials to slot in. Viewers often ask where to start and how the two relate; watching the 13-episode run first, then the 10-episode set, keeps Alucard's story in order and lets the later, more faithful retelling build on material you've already seen. Two entries, one clean sequence, and no extras to guess about — begin at the first episode of the original series and work straight through to the end of the second.
