I've always stayed about a season behind on Agents of SHIELD. I like how it stayed parallel to the other Marvel movies though. This is just like the comics: a minor title following the main action in the other books. Like a minor title, it's hardly a must read if you're short on pocket money.
I enjoyed season 3 on Netflix but realized about half way thru that it reminded me of season 3 of Angel!!! The recycling of themes goes on and on in the Whedonverse. I'm not sure why Marvel wants to persist with Ghost Rider though. He has always been a minor dark character with little upside. I think Joss should have fought for Agents of SHIELD :Angel and Spike. This would have been much more entertaining and caused a true Geek Gasm.
While i enjoy the latino GR (Joss pushing the diversity....They should make all Marvel characters adopt new ethnicity and make the Black Panther a reformed Klansmen who uses his superpowers to fight racism!!) I miss Nicholas Cage's scene and vicodin chewing from the sequel. I'm all up to date. It's no GOTHAM.
