Yeah, pretty much anything by Dream Theater is going to be challenging, but Pull Me Under is one of the more manageable songs.
Just like bbzswa777 said, there are some difficult runs, so a good approach can be to just focus on the main riffs at first and add the speedy solo parts later. It's a fun song to play!
