Shows are expensive to make period it just depends what is your "catch", drama's can be also very expensive to make especially historical ones Broadwalk empire has nearly the same budget as GOT, Rome (the HBO & BBC one) was the most expensive show ever made besides friends which had a budget of over 10M$ per episode because much of the cast was being paid over 1M per episode.
It's not always the budget it's also the production Firefly managed to make very good use of VFX with relatively "small" budget, BSG didn't had an explosive budget either, Star Gate had also a relatively small budget with the VFX heavy episodes having less than 400,000$ effects budget they just used it rather well.
On the other hand you can have very high budget shows looking like B-movie quality, Terra Nova, Falling Skies and Fox's attempts at scifi Almost Human (which was a freaking amazing show and Fox exec's need to pay in blood) and their current Minority Report shows are very expensive but have very low quality looking effects.
And if you want the best example of how budget can easily be misused well then Agents of Shield had a 14M budget for the pilot and even the per episode budget was considerably lower it was still pretty damn high and they still managed to completely cock it up both in the visuals and the story/plot departments.
IF they'll build a solid production team hopefully there are some folks at Paramount Television that worked on previous shows and are still either alive and or working in TV production and give them budget and creative freedom to work then we might get a good product, if this is going to be brand managed like AOS then it's going to be completely bonkers.
AOS is tethered to the cinematic Marvel's universe and it's it's biggest flaw, it's plot is completely dictated by the movies and it spoiled Cap 2 for me and just became a running joke.
Agent Carter was considerably better because it was set back enough in the past that they can do anything without having to tie it in with the movies.
And this is my biggest must have for this show, either put it in the original canon, reboot it again, or throw it so far away from the movies that it couldn't touch them with a 10 foot pole or don't make it at all.
