For some inexplicable reason, partway through The Avengers, director Whedon and his cinematographer, Seamus McGarvey, decide to switch over to really bad DV. The entire movie might be DV, but the middle section is painfully obvious. With Tom Hiddleston’s British machinations, it feels like the biggest, strangest (and possibly worst) “Masterpiece Theatre” ever.

While Whedon’s responsible for a lot of the film’s problems–the lousy first act, the utter absence of character development, some of the least ambitious direction in motion picture history–some of the problems came with the project. Sam Jackson isn’t just ludicrous, he’s bad. Scarlett Johansson as a Russian? And a super spy? It’s absurd.

But Whedon doesn’t give his better actors much to do either. Both Chris Evans and Robert Downey Jr. meander for the first half, though Evans is a little better (Downey recovers in the second half). Mark Ruffalo does better. Chris Hemsworth barely makes an impression; his appearance feels contractually obligated more than anyone else’s.

The movie does come together eventually though and Whedon does come up with some really funny scenes. He starts the movie incompetently small and then brings in the spectacle. The spectacle works, regardless of his direction, it’s just too bad The Avengers isn’t a cohesive work.

Hiddleston’s pretty good as the only non-CG villain and Clark Gregg does great supporting work. Jeremy Renner’s minuscule presence is inconsequential; Cobie Smulders is terrible.

Alan Silvestri’s score is dreadful.

But, as I said, The Avengers spectacle does entertain. Eventually.
