Attack on titan is a truly impressive anime if you are in there for unique story and different set ups. This is not like your regular shonen anime where the protagonist gets random powerups hell no! If you are new to anime I would definitely recommend watching it. AND dont just judge an anime by the first season I would agree that the first season is just dumb action and Mikasa shouting Eren. But just hang in there its just going to get better. Yes this is not the best anime or anything but don't go down by the people rating it 1 star, seriously? did they even watch anime?? I would say they are just out right haters. Hang in there all your questions will be answered. And not to mention the 4th season the protagonist Eren will only get better and even Mikasa too. This anime just gets better season by season. Not to mention the sound tracks they are some of the best tracks that I've heard. Watch this anime you many witness one of the best written show. PS there are no plotholes. Those who are saying that there are plotholes are just those who haven't completed the anime. Some of the early chapters have foreshadowing from as far as 120+ chapter. The writer has planned it out so well. Give it a shot you may not be disappointed.
