A fun way to spend 63 minutes. There's enough insightful and contemplative content here to recommend it over many longer feature films. If it sounds interesting to you, watch it.
The 13th film in the Marvel Cinematic Universe is an effective and purposefully crafted introduction of Phase Three; New characters, new storylines, and new dynamics between existing characters. While it may have benefited from further editing, this is mostly an exciting summer blockbuster with the Marvel humor and playfulness we've come to expect.
No need to see this one in 3D or IMAX.
One of the worst written movies I have seen recently, but it does have some nice shots invoking German Expressionism and some interesting homages to silent horror flicks. Overall I could only recommend this movie to hardcore horror fans and those interested in the special effects evolution of shoestring-budget horror cinema.
