I like the way Future Imperfect started but I think it lost steam toward the end. Like they had this great premise for Riker to wake up 16 years in the future with no memory, but couldn't figure out where to go with it so they made it a 'loveable misunderstanding'.
I also like Inner Light but unlike most would not rank it among the best TNG episodes.
Frame of Mind might be my favorite episode like this.
Hard Time is another good one, and an outlier because we know it's a fake reality from the beginning and it's all about the emotional impact on the character.
