Anyone else get a little put off by amnesia/memory wipe stories?

I’m not referring to shows that *start* with a character having amnesia, I’m talking about shows that take established characters and make them forget things we as the viewer have already seen play out onscreen. I find it frustrating because usually one of two things happen as a result. Either the characters lose that character development (making all the character work done prior to that feel pointless), or we have to watch them relearn something that we’ve already seen them learn once.

I realized this when watching Gen V. Around the 4th or 5th episode, the main characters get their memories wiped and forget pretty much the entire main plot thus far. While I’ve liked the show so far, it made me realize that I hate having to watch characters figure something out again or repeat things we’ve already spent several episodes watching them do. It just feels like a slog and a pace killer because the viewer already knows what happened. And while this particular mind wipe is used to lead the main character to a big reveal, her mind is then immediately wiped *again* leaving the viewer as the only one who knows what happened *again*.

I’m not saying it can’t be done in creative ways that advance the plot (I thought this newest season of Loki did it pretty well), but I’d argue that in most shows it’s used as padding and to create fake tension. What are your thoughts/egregious examples?
