Personally though, I loved it. The pilot episode was, I thought, an epic genre treat - the Marvelverse meets Buffy - and my only concern was whether the show could keep up the quality week in, week out.
Week two's outing '0-8-4' - which follows new consultant Skye's "first day at school" as SHIELD uncover a powerful piece of forgotten tech - is all about Coulson's new team. Fractured and frequently at each other's throats, our heroic sextet break apart before uniting against a common threat and coming back stronger than ever.
It's a tried-and-tested device - as is the 'Skye as reluctant mole' sub-plot - but it works here, repackaged with a new and very pretty lick of paint.
The flaws in the show that critics picked up on last week are, it has to be said, present again in '0-8-4' - Clark Gregg remains great value as Coulson, Chloe Bennet 's Skye is as sparky and fun as she was last week, while Iain de Caestecker and Elizabeth Henstridge are an adorable bundle of fun as charming duo Fitzsimmons.
But Brett Dalton is a little bland as hard-headed Grant Ward and Ming-Na Wen's Melinda May might get more of a chance to unleash her kung-fu skills this week, but never threatens to develop anything approaching a personality - she's a bad-ass blank slate.
Still, the whole thing is put together with such finesse, in such a fun and glossy package, that you find yourself forgiving the show its flaws. Hopefully the few problems the series has currently will resolve themselves, but for the time being, there's more than enough here - action, laughs and geeky nods to the wider Marvel universe - to keep us watching.
It may essentially be a glossy procedural, but there's nothing else like Marvel's Agents of SHIELD on TV - at least not currently. It's a weekly comic-book thrill-ride and two impressive weeks in, I'm going to keep on saying nay to the naysayers.
Oh, and I can't wrap up this review without mentioning Samuel L Jackson's fantastic Nick Fury cameo - as much fun as it is to name-drop Iron Man and the Hulk, scenes like this really help to solidify the link between Agents of SHIELD and the Marvel cinematic universe.
A movie / TV crossover on this scale has never really been attempted before - it's something genuinely new and exciting, and how often can you say that about something on US TV these days? Robert Downey Jr, Chris Evans, Scarlett Johansson... I can't wait to see who turns up next.
Make mine Marvel! - This week's Marvel easter eggs include... references to Captain America, Tony Stark, Thor's hammer, the Tesseract, HYDRA *and* gamma radiation.
Coulson lives! - More hints this week about Phil's big comeback. The way he keeps repeating that Tahiti mantra ("It's a magical place"), it feels almost like a pre-programmed response. Almost... robotic?
