The first handful of episodes actually set up a really promising start to a potentially groundbreaking isekai. It's also the only anime where a tsundere dragon gets vored by a slime, so I definitely have to give it credit for that.
However, as the show enters the 10+ episode mark, a critical issue becomes apparent. This issue is the fact that the show's writers don't care about the new side characters that are introduced for Rimuru to help with, yet at the same time expect us to care. For some unexplainable reason, the show decides to have some generic shonen fights, perhaps in an attempt to get some free publicity from "Epic Anime Fight Scene Complication #12 2019" on YouTube. Yet nothing about these fights is epic. There are no stakes, no "wow" moments, no memorable punches...they're just sort of there.
By the end of the series, I really didn't care about what Rimuru was going to do to save the day this time. The fun that was present in the beginning of the series had pretty much diminished as it churned out tropes that could probably be found done better in fantasy shonen from a decade ago.
Despite my harsh criticism over the overall atmosphere/my enjoyment of the series, there are redeemable elements that belonged in a better series. Rimuru is a bit overpowered, but overall a good character. Shizue, the goblins, the wolves, Millim - all of them could've set the ground for a really good fantasy series.
The best way to describe Slime overall is "so close, yet so far." In the development of the series, an essential checkmark was clearly missed before releasing it: "isn't freaking boring."
