About Time - Dropped it after episode 1 due to the singing.
Rich Man Poor Woman- Dropped it after episode 10 due to the lack of progression in plot, lack in the romance/chemistry department, repetitive and boring OST, Suho's acting as well as character, the whinging female lead, too much screen time for female second lead (you'd think she was the first), pointless side storylines.
Miss Hammurabi and Between - I'm thinking of dropping them because I'm finding them a bit too boring and I haven't looked at them in weeks.
