Pandaman284’s review published on Letterboxd:
20/30. Blue Submarine No. 6 was always one of those classic Toonami shows that I was a bit to young to have seen when it airs but always used to hear about as a kid. I gotta say that the CGI was actually better than I expected, I mean it still doesn’t look super great and hasn’t aged to well, but if I was watching this in 1998 I probably would have been pretty impressed. I like the main character and the setting was really cool. I think the story may get a bit to exposition heavy and slightly preachy at times, but overall I enjoyed it and I think the ending was good. Overall I think it’s definitely worth a watch if you’re interested.
