It’s not a bad movie but it’s a really unfocused movie with a lot of subplots and characters. Hard to keep track. This might have been better if it released and edited as a mini-series.

A great set up to an interesting saga. Lots of storylines that will come together over the course of the next three films. Can’t wait for the second installment in August!

Well-acted as far as superficial characterizations allow (Costner and Jon Baird share screenplay credit) and impressively mounted for a wide-open-spaces pageant that, quizzically, was not shot in widescreen, “Horizon” is most successful at filling its frames with ambition.

The first chapter in Kevin Costner's epic western series is a meandering, regressive snooze.

Costner is fully in traditionalist mode here, painting a quote-unquote sweeping American saga that feels like an expensive miniseries compressed into feature form.
