Bad things happen to good people. That's just a fact of life.
This wasn't just bad things, this was a convoluted ridiculous set of circumstances that only make sense if an evil God had it out for Ripley.
Seriously our heroes have to be dumb enough not to check for more aliens before going into hyper sleep, the egg has to decide to open with no one near it (something they've never done before) instead of just getting some poor bastard on Earth when they get there so they can wreck the ship and kill off three characters just because, and somehow the face hugger can navigate from the egg's hiding place to the hyper sleep chambers, and then survive implanting Ripley long enough to implant a dog/cow instead of dying like they usually do just so they can have a alien run around (a bit after Ripley should logically be dead) and still give Ripley a reason to commit suicide.
It just comes off a putting everyone into a corner just to surve the plot.
