I thought Snake Eyes was cool and the action and animation was great.
I hate when deaths happen off screen but not when they happens on screen.
My main dislike about this cartoon was that they removed the nuances and personality in the characters making it a more primitive tale alltogether. Adult does not just mean more sex, violence or swearing but American audiences are so starved for these things that they like any kind of product that comes along containing these things. People died all the time in the comics too but it was done in an plausible manner atleast in the marvel series, the devils due series tried to create the shock value a bit. And it did not work. Deaths should have a point even if that point is that death in war can be senseless and sudden. It is not just GI Joe that have gotten more stupid movies and comics in general have less depth now than they had only ten years ago. A comic about Spiderman and Doctor Octopus working to get eachoter to beg for mercy comes to mind. On the other hand death and sex does not mean that the story become more childish either but most often they do.
I also suspect for whatever reason that there was a last episode cut from the show. Either because the animation team could not finish it on time or because Hasbro dont want to pay for it.
