I think they could've paid more attention and time and money especially in season 2 considering there is a lot of time traveling and CGI work needed in series 2. Some of the scenes look almost filmsy due to the cheap looking production set, lighting and whathaveyous so at times it was hard to get into the atmosphere of the show because the cheap set design was distracting. Story like these need a bug budget to build a realistic world but I think the series just about barely manages that which is a shame otherwise the series in itself is ok.
