Personally, I feel that TP is one of the best zelda games out there. It had a huge overworld, a lot of variety in dungeons, items, and puzzles, a great storyline filled with memorable characters, has great atmosphere, and is just a really solid zelda game as a whole. I feel that people too often look at some qualities that could have been better, and tend to exaggerate about how bad they really are. For example, people often say that dungeon items were practically worthless after their respective dungeon. The only items I found myself not using much were the dominion rod and the spinner, and even then I did in fact use them after their dungeon (Ex: I had to use the spinner to get to a piece of heart.) Another thing people say was that the music wasn't very good. While it's true that the music wasn't quite as good as OoT's or Alttp's, it's soundtrack was still amazing. I often find myself listening to the overworld theme, the Lost Woods rendition, the night time theme, and the various themes from the battle with ganondorf. One other thing people complain about is that it''s too easy. To this day I don't really get this one. It was perfect for people new to the series at the time (such as myself.) Even after beating some of the hardest games in the series, I still don't find it too easy. A lot enemies used more strategy than ever, which I feel is better than just having the enemy do 5 hearts of damage to you and have that serve as the difficulty. For example, fighting the three darknut on the last floor of the cave of ordeals required quite a bit of strategy, because if you rushed in blindly, you're likely to die.
While I could go on defending other aspects of the game I actually liked such as the motion controls and the graphics, I feel by now I've made my point about how great a game TP really is and how people really shouldn't focus and exaggerate on the bad qualities so much.
