They could have had Skye make a BttF comment and Coulson correct her, but maybe they didn't have time. I enjoyed all the Whedon wit and humor. The story felt like a promise of something, not an actual something; maybe that'll turn out to be bad, but I don't think so. I think it's better than every pilot that tries to cram in the highest possible stakes and biggest set pieces in with the exposition and just ends up overburdened. Sound editing needs work. The soundtrack was too high too often. Introducing a super-powerful truth serum in the first episode's not necessarily a good idea; now he's going to have to periodically write excuses why it can't be used to solve the problem of the week. Don't think it was worth that, just for that one gag and twist.
