Growing up, I had friends who were really into anime. I just never got into it as a kid for some reason. I remember my friends going crazy over Vampire Hunter D, Ghost in the Shell, Cowboy Bebop and stuff like that. I'm a very big mystery fan in general -- novels, movies, tv shows, games, etc. In doing research, I found that there are a lot of good mystery stories told in anime. I decided to start with something that seems to be pretty universally liked in Death Note. I figured 'ok, if I can't get into something that so many people like, it's probably just not for me.' I'm 12 episodes into Death Note and have found it to be very good story-wise. I like the premise and it definitely has an air of mystery around it. I was recommended Death Note, Monster, Erased and Detective Conan.
The catch for me is that it has to be dubbed because I do the majority of my watching while I'm working, so I put something on my second monitor but I can't pay 100% attention to subtitles. I know there's the argument of 'subs vs dubs', but in my case, I really don't have a choice, so I have to find stuff that is dubbed or made in English originally, which isn't as common.
Anyway, if anybody knows of some anime that fits my very specific criteria of stupid American boy English and mystery in theme, I'll be happy to check out anything, whether movie or series. Detective Conan (Case Closed) caught my eye because it has 1000+ episodes, but apparently only a small fraction have been dubbed.
