Knowing that it's an update/sequel to an early 90s series, I'm inclined to forgive it somewhat for its repetitious gameplay, heavy backtracking, trite dialogue and plot, and bland characterization. The voice-acting leaves much to be desired. Monster closets are its stock in trade, though I'll admit to yelping at some cheap jump scares.
The isometric camera is fine, and the camera only becomes frustrating for the moments in which the designers decide that this inexplicable angle is most appropriate, and you're stuck with it until you progress to the next area. As in, the camera pans to face you head-on as you move down a corridor -- you can't see any enemies more than two feet ahead of you, and if you happen to spot some behind you, you have to spin around and take them out, anyway. There's an irritating boss fight with a fixed camera, making it more challenging than it ought to be.
That said, it is a graphically beautiful game, and the set and sound design are well-done. The shots you get of the area surrounding the ship (the planet in the distance, debris burning up, or thrusters firing) are lovely and detailed, and while the alien sounds are (like the monsters themselves) repetitive, they are evocative, and the other environmental cues are thoughtfully done.
If you enjoy the grind, or end up with this in your library and want to knock one out of your backlog, here's my advice: keep your expectations low, play for short sessions, and just power through it.
