I rate books based on the traditional 5 stars system.
★★★★★……………… 5 stars: extraordinary; perfect; brilliant; I will read it again;
★★★★………………… 4 stars: loved it; almost perfect; probably I will re-read it
★★★…………………… 3 stars: liked it; nice ideas; could’ve been better; some issues
★★……………………… 2 stars: mixed feelings; don’t like it, don’t hate it.
★………………………… 1 star: didn’t like it at all; terrible
