I don’t know how anyone could rank the Mandalorian after only one episode.
Same, like I get a lot are excited (and dissatisfied), but it’s just one episode. Not only are there more episodes coming out, but some of those episodes will be directed by different directors which I’m sure will greatly impact how it unfolds; good or bad, to be determined.
Not just that it’s the first episode of many more, but it is also merely the first ‘chapter’ of an 8 chapter story. We don’t know yet how it will unfold, and one’s opinion on the quality could change greatly once they see the full picture.
