I enjoyed them for what they had and what they where. Flaws aside, I jumped in and enjoyed every single bit of it, the ending of ME3 wasn't what I was expecting, but I wasn't too disappointed because the over all experience was so darn great.
I guess everyone complaining about the ending so much, when I got there I didn't have my hype to high so I was perhaps a little disarmed, and lucky because I got the extensive ending first... I do admit if I had the original ending I might have had more question marks over my head. Not the best ending ... clearly, but I can't hate the game because the journey was great.
And the universe they built was great, I can't wait to see more of that universe.
