Think my earlier review was a bit too harsh, but ultimately can't see this movie reaching higher than a 6.5.
The aesthetic vision feels completely disorganized. Some of the comedic moments feel a bit forced, as does, in some cases, the team's angst toward one another and the "ticking time bomb" plot. I think I just dislike Whedon's directing style compared to Favreau, Johnston, and Branaugh (and, of course, later, Gunn and the Russo brothers).
Loki is much less sympathetic…
