Bubblegum Crisis Toyko 2040

Apparently the OVA Series is a much loved classic, there however a debate on Tokyo 2040 being any good even though its a remake kinda, its about 50-50 on the review boards that I have read. I can't say much since I haven't seen it myself, however I guess for continuities sack watch the Orignial OVA Series and Season 2 then Tokyo 2040.
