For me, "S.H.I.E.L.D." started to really get good around a Season One episode called (1.13) "T.R.A.C.K.S.".Most series‘ take time to develop and in a lot of shows fans can pinpoint when a show really finds its stride and “gets good”.
When would you tell someone that SHIELD gets good?
Your argument against Marvel started off strong then fell off a cliff when you mentioned Runaways and Cloak & Dagger.It doesn't. Marvel Cinematic Universe TV shows are by and large not very good, with some exceptions:
Daredevil seasons 1 and 3
Jessica Jones season 1
Cloak and Dagger
Punisher is okay.
Agents of SHIELD, Inhumans, Iron Fist, Luke Cage, Defenders, the other seasons of Daredevil and Jessica Jones, and Agent Carter are just plain boring.
Marvel generally stomps DC at the theaters but on TV DC is king. Doom Patrol, Watchmen, Swamp Thing, Stargirl, Black Lightning, Lucifer, iZombie, etc are all orders of magnitude better than Marvel's output. iZombie is especially good if you're a Buffy fan (it's made by the creator of Veronica Mars).
I disagree. All of those shows have a strong idea about what they want to be and strong ties to their source material, and they execute their visions well. Agents of SHIELD is a comic book show that starts out ashamed to be a comic book show at all, and as it goes along it just becomes a generic substitute. Characters nobody cares about masquerading as comic book heroes like store brand cereal.Your argument against Marvel started off strong then fell off a cliff when you mentioned Runaways and Cloak & Dagger.
Ditto with yer DC argument. BTW - if yer curious 'Stargirl, Black Lightnin...' is where the wheels fell off the wagon.
