As most anime adaptations are in the type moon universe, it's not the best. At least in most peoples opinions. Really just fate grand order in general has had trouble (except for Babylonia) being adapted. I can't give my opinion on the Solomon movie yet because 95% of people in the west haven't seen it and that goes for me too, but from what I've heard it's great. But yknow what, it's not like horrendous or anything just mediocre for a fate movie so go ahead. It's probably a bit of a different experience if you've not played through camelot on fgo.
