There's nothing wrong with it. However, the first time you use aptitude, everything will be marked as manually installed. When you tell it to install things, it will bring in what is needed to meet dependencies. Whether or not it considers 'recommends' as dependencies is selectable from the interactive menu (or a config file in /etc).
Two common problems:
If you mix with apt-get, apt-get will work but all packages will be marked as manually installed in aptitude (actually, the won't be marked as Automatically installed). This leads to the cruft buildup that aptitude is suposed to help you prevent.
The other problem is this. Install package A. Aptitude brings in package B to meet a dependancy. Over time, you get attached to package B in its own right. Later, either package A changes and doesn't need B or you remove A. If you haven't told aptitude that you want to keep B, it will go ahead and remove it too.
In interactive mode, you get a detailed preview (with reasons) of what aptitude wants to do. You can then edit that preview to fine-tune it before telling aptitude to go ahead. It really tries to protect you from yourself without preventing you from shooting yourself in the foot if that is really what you want to do.
When running stable, the problems don't show up too frequently. However, when Etch was testing, many people were using aptitude for the first time coincident with shifting package dependancies. There were frequent posts to the list like "Aptitude wants to remove 150 packages!!!". They were using the CLI and didn't get the detailed explanation from aptitude that they would from the curses interface.
