It's not as hard as everyone makes it out to be, sure. You have to come into school with good study habits and time management skills. People that struggled with those issues in undergrad who never changed will find CRNA school impossible to manage. If you've got those under control, it's very doable.
I think time management is the worst part. Waking up at 4 AM to be to clinical, then having to leave clinical to go back to school for a seminar, then back to the hospital to go do your pre-op's before even going home only to have to be back at the hospital in the morning doesn't leave much free time. You have to be focused to study on a tight schedule like that.
It is not impossible to get into school, but the further I get in my program, the more I keep hearing finding a job is more about where you went to school. Finding a job as an RN, it really doesn't seem to matter where you went, or whether your BSN is from an online program or a brick and mortar. For those who think you should just go to whatever school will accept you, think about it first. If the school is easy to get into but has terrible attrition rates or is known in the area for cranking out students with poor clinical performance, you're doing yourself a disservice.
