So I just finished up episode 13 which, according to MyAnimeList (http://myanimelist.net/anime/2251/Baccano
!), is the last episode. It list the next three episodes as Baccano! Specials (http://myanimelist.net/anime/3901/Baccano!_Specials
So my questions are basically: Are these three episodes worth watching? Are they canon? Are they very important to the story? And should I watch them before I write a review/recommendation for the show?
The reason I'm asking this is because, even though I thought this anime was alright, I'm ready to be done with it; however, I once I set out to watch a show, I always finish it unless: 1. Its really long, and can't hold my interest. 2. The latter episodes were never dubbed in English.
