This was actually good. It would've probable been better had it been in a more American-style (non-CGI) animation, instead of anime, but overall a great product by Marvel. The characterization was perfect for Punisher, and Widow had a personality. Those "Avengers" are just window dressing, and there were some good cameos.
All of Marvel's animateds aren't trash - Thor: Tales of Asgard is pretty good, the first half of Doctor Strange is excellent, Hulk vs (Wolverine) is good, Planet Hulk and Next Avengers are also good. The need to bring in Nick Fury instead of always using Samuel Fury.
