There are no IMDb or TVDB entries for this show. The entries on IMDb and TVDB are for an anthology series that does not actually exist. Those databases are listing both "DAHMER - Monster: The Jeffrey Dahmer Story" and "Monsters: The Lyle and Erik Menendez Story" as two seasons of a single TV show when in reality they're the first seasons of two separate TV shows, per the Netflix website.

If TVDB and IMDB have both seasons in a single series, why not give both TMDB series (113988 and 225634) the same TVDB and IMDB ID?

2 reasons :

• The first is technical. You can't have 2 times the same IMDB or TVDB in the database.
• The second is logical : The definition should be similar on the 2 sites to set the foreign Id, otherwise many third party apps will not anymore work.
