Telekinesis is the best power prove me wrong

Telekinesis is the best power both defensively and offensively. You can will things to you to protect you. You can manipulate yourself up and away from danger. You can throw things at your attackers. So why is it in all the superhero movies right now there's not a single one who's got Telekinesis and using it to its full ability? Hell the only one I can think of is Jean Grey and even she hardly uses it instead opting for her telepathic abilities. I see no downside or negative flip to telekinesis so why isn't it used and why isn't it such a great power?
