Metroid: Other M

I need opinions. Ever since the game got announced I've been having really high expectations for it, then people started getting it early and started reviewing it...badly. I haven't played it but people have complained about it a lot.
There have been complaints about combat, exploration, suit/weapon upgrades and such. All of this makes me doubt that the game is worth buying, but I'll never know if I'll live with the problems or just downright hate them when I play the game.
I dunno if I should rent it or buy it. I'm a fan of the series so I should buy it, but what if I hate it? Rent it of course, then if I love it buy it. It sounds like a simple decision yes, but I still don't know what to do D:!
