As far as franchised products based films it's very rewatchable and I imagine will be a comfort movie on the future.

Id put it just a little below the Lego Movie for quality for what's essentially an advertisement movie. No complaints however.

As a D&D fan it hits the sweet spots of references but not to feel like it's pandering (see Super Mario Movie). What they add is at least relevant somehow. For a die hard D&D fan you can feel the die rolls going on in the movie.

I imagine Hasbro will kill or ruin Studio One somehow which is a shame I would want more of these kind of D&D movies
