It was bad ending, but it wasn't as bad as many people make it out to be. We got a whole season of meeting the mother and it was great. The last episode, while it does undo a number of things, isn't really important to the overall story. If you just ignore it, or if it never happened, everything else still works.

The fact that you can and probably should ignore the finale still makes it a bad episode and a bad finale, but it doesn't retroactively make the rest of the series pointless and it doesn't answer any questions that weren't already answered.

Idk. Was it really a season of meeting the mother? It was more a season of

Spoiler below

Spoiler

Barney and Robin planning on getting married, married for a very brief time, mother met finally, killed off, then him going to Robin. Very abruptly too (in the last couple episodes.)

It definitely to me was a clear waste of a season and entirely ridiculous. This guy talked about his whole life up to that point to where he finally meets their mom and... Then just goes to Robin? Even the Ted actor said he couldn't believe they were still doing the original ending.

I don't see it much different than people never wanting to rewatch GoT- knowing the ending is awful definitely makes you think why bother, at least for me.
