I watched it last night in digital projection and I was sitting close to the screen. Not the best combination, the resolution lines were clearly visible.
I liked it...but the ending was... not ok.
Black holes are unapproachable, the event horizon is annihilation in it's purest form. No imaginary human has any business even closely approaching a thing like that and live in any imaginary story that takes place in the next 10000 imaginary years.
I would watch it again in true Imax.
