I've used linux for about 8 years now. The only time I've had a catastrophic failure was with a disk drive went south.
About the only times I've seen ext2fs require manual repair is a crash/power failure during fsck on boot. It doesn't happen very often. Even then, it may not be a serious falure, just the type of error that requires a choice in fix - missing inode/partially written inode in the root file system will usually require the choice of deleting, or putting in lost+found.
No file system is immune to that level of failure. Some are better at hiding the damage (xfs will lose free data blocks like mad - 3 in a row lost 6GB out of 12, though no used data was (visibly) lost.
15 minutes isn't that bad - wait until you have to spend 30 minutes to 3 hours on an NTFS or FAT32 rebuild, only to find you have to reinstall.
