If you like movies that maintain a slower-paced beat and depicts life as it might realistically be, living on a space station (without the few sentimental blandishments), plus George Clooney giving a metered performance, this might be for you. If you're expecting Michael Bay or a Spielberg rollercoaster, and possess a short attention-span, stick to Disney/Marvel/SW flicks.
Many predictable scenes but they weren't aiming for 2001 here. With the exception of a few curse words from Clooney, this is a great film to watch w/your kids (if their attention span has not already corrupted by lightning-paced movies or video games). The 4 rating is for those who choose to watch it w/kids. If you want whizbangpow, stick with Wonder-Woman-Riding-The-Retro-Stranger-Things-Nostalgia-Gimmick.
