This series of intro modules serves as a good intro not only for new players, but also for a new DM. There's a good mix of combat and thinking required. The combat scenarios take place over a mix of different environments, including in the trees. The issues I have with the module (and thus rating it a 4) is that the interaction within the town seems a bit stilted with the main NPCs who run the town. They are extremely stereotyped and one-dimensional. Also, there's an issue where you really want characters to be at 2nd level when they start the 3rd mission but they don't quite have enough XP if they've only played In Volo's Wake. They are just short. However, there are the standard rules for adjusting the challenge rating and that helps, but the DM still has to be careful.
