I've seen all the other movies apart from Khoon Bhari Maang.
Tezaab was the best movie. This film was series stuff with lots of intensity. Plus, it had a good story as well where Anil Kapoor turns criminal after being framed and arrested. Plus, it had romance as well which was superb as Anil & Madhuri shared a wonderful chemistry. They've done many films together but this their best movie they have done as a pair.
Anil has given many great performances but in my opinion, this was his second best (Nayak being the first). He did a brilliant job balancing his series role and romance at the same time. I just love college scenes especially the part where he attempted suicide.
Qayamat Se Qaymat & Shahenshah were memorable films but Tezaab was better.
Btw, this was the best song in Tezaab.
