I have no problem watching this for free somewhere someday

if you have a chance to see it in imax, i think it might be worth the cost.

i did find the 2nd half of this to be a bit of a slog to get through, but it has plenty of great visual moments, & a nice if perhaps slightly cliched score that benefits from being heard on a very loud system.

Nope, this needs to be skipped. There is only one place that would be excellent to see on Imax. Of course, I'm speaking about Neptune, very spectacular. You factor in the excessive cost of Imax and an entire movie of bland and meh scenery. Don't do it !!!
