Good enough, though definitely could've been better.
'Ten Who Dared' is pretty reminiscent of 1959's 'Third Man on the Mountain', with a dangerous exploration being riddled with in-house arguments. In comparison to that, I think this is inferior. There's still enough here to enjoy, albeit marginally.
I didn't really connect with any of the characters, none of the actor performances blew me away either. John Beal as Major Powell is the most likeable, alongside David Stollery's Andy. The one who I actually rated most, though, is Brian Keith as Bill - not so much the character, more so Keith himself.
The shots of the Colorado River and its surroundings look pretty nice, but overall this film is just missing things that stop it from being greater. I've seen worse from Disney, that's for sure.
