Agent's of S.H.I.E.L.D. starts out pretty bad. Very flat characters, often cheap plots. About half way through it became good though. It's low-power, so no worries about super heroes.
Capatain America 2 you need to watch for the last third of the show to make sense ;)
Guardians of the Galaxy will be the first comic movie I'm really looking forward to. It's not a superhero comic at all and the main characters have a personality closer to the firefly crew than anything else (That's assuming they are staying close to the comic).
I didn't find the CGI distracting, nor is Rocket treated like Jar Jar Binks (he is actually one of the more "serious" characters). Although I will admit that Groot (the tree) has some Jar Jar Binks style moments, but it isn't as distracting/jarring as Episode 1.
The last movie I laughed this hard at was The Avengers. However much like The Avengers this too might have weak re-watch value as you'll know the jokes are coming.
I am looking forward to the sequel and want to watch it again as soon as it is out on DVD/digital.
It has like 90% on Rotten Tomatoes and 9/10 on IMDB. Safe to say this is another smash hit and another feather in Marvel's cap.
It's really sad that the star wars prequels may have hampered the adventure/scifi genre for the better part of a decade.
I have no problem with the gimmicky, comic-relief character if there's some actual substance there.
Edit: and the recent Batman trilogy. Untouchable by comparison.
My favorites super hero movies are not Marvel, I would put The Dark Knight at number 1) and Watchmen at number 2).
I'd say skip them and watch Watchmen from 2009 and/or V for Vendetta (both DC graphic novel adaptations). Both are written by Alan Moore, much more heady/thought provoking than the Marvel offerings.
Also, indirectly 'Comic Related', the excellent BBC show Utopia is worth checking out (it's slate to be remade for HBO coming in 2015 with David Fincher at the helm).
Iron Man is okay standalone, in the same way the first Spiderman movie was okay. Everything else is a skip.

I'll give GOTG a go out of interest.
