what do আপনি think is better negima the book অথবা negima the প্রদর্শনী

I think the book because it has আরো action and its really interesting.

the book, the প্রদর্শনী pales in comparison.

The one I saw was a complete mess. It started out good, দ্বারা following the basic storyline of the book, only in যেভাবে খুশী order and with small changes.
That is, until about halfway, when they started making big changes (to fulfill there own sick fantasies) and skiping important events from the book. They even skiped a, now major, character altogether. দ্বারা the end, they had completly stoped following the book and made up there own storyline that was complete bullshit. And they even gave it the worst, most cliche villain ever: The Devil. (WHAT!?) There was never any mention অথবা even hint of The Devil before, why is he suddenly the main villain? It was so bad it was almost unwatchable.

Also, the book is still ongoing. So.... yeah.

I haven't read the জাপানি কমিকস মাঙ্গা yet, but I have watched the প্রদর্শনী and I like the প্রদর্শনী a lot more. :D
