I'm sorry could you clarify what you mean here?
Is it charging me full price for entry and running for a feature length amount of time? Then yes. A film needs to stand up as a complete movie even when it's a sequel or a middle child. You really can't take an extra long movie chop it in half part way through and then call it "complete". Also I lay a lot of flaws at the feet of reloaded I might need clarification here on which one also applies to Two Towers.
You keep saying this, but a movie being up your alley doesn't make it good in it's own right. It just means it's something you are more likely to overlook it's myriad flaws.
